Impossible to know or not. They may be glued together and therefor don't need the perceived stack. Also, we don't see the back end, if it's glued together it could have basically any shape on the back. If it's solid, and doesn't try to trick the viewer, it's possible to calculate, although I don't really wish to do so unless OP can confirm that we're not getting tricked.

Nigga where the hell did you get 495?
>>710363885
I figured that it was a sign, seeing as that is both the weight of your mother and the number of times that i fucked her.
>>710362889
Mist be 83
The answer is definitely 330. No other answer.
>>710362889

My intuition suggests approximately 650
>>710362889
Pascal's Triangle to answer this, 165.
Bro, i used pascals triangle and got 330 the fuck are you talking about?
>>710363885
He was including the ones below ground level that we couldn't see. Kek
>>710362889
None. Those aren't bowling balls.
>>710363211
No tricking, found pic on web, being curious, asking fellow /b/tards.
summation from i=1 to 9 of i!
>>710364212
This is correct.
Once you figure out the outside number, you add the number from 2 levels above it for the interior count of balls.
1
3
7 (6 on outside plus 1 for interior)
12 (9 on outside plus 3 for interior)
19 (12 outside plus 7 interior)
Etc etc.
That's the pattern.
>>710362889
Balls in one layer: (n^2+n)/2
(1+1)/2 = 1
(2^2+2)/2 = 3
(3^2+3)/2 = 6
(4^2+4)/2 = 10
(5^2+5)/2 = 15
(6^2+6)/2 = 21
(7^2+7)/2 = 28
(8^2+8)/2 = 36
(9^2+9)/2 = 45
1+3+6+10+15+21+28+36+45=165
There's 165 balls.
>>710362889
All of them
>>710362889
About 5
the summation of the third line of pascal triangle diagonally is the answer (since there are 9 rows of them that means you need to add 9 of the numbers)
>>710363182
Fucking moron
>>710364310
Can't be a triangle, look at marked angles. They are 45 degrees, more or less, hence square. If triangle, angles would be 60 degrees.
>>710365568
Fuck, forgot pic.....
>>710365239
>(4^2+4)/2 = 10
Look closely at that 4th layer - and then defend the notion of only 10 balls.
>>710362889
There are 81 visable bowling bowls, anything else is speculation.
>>710362889
Man, this ain't bowling balls!
This is a digital picture!

>>710362889
assuming it's entirely bowling balls.. 165
assuming it isn't.. 81
so anywhere between 81 and 165
>>710365631
>>710363095
He means in the center of the pyramid, dumbass
81
no reason to assume balls that we can't see it could be a platform
thats gotta be at least ten.
>>710366293
You are a retard, do you know that? I know the maths when it comes to angles, you shithouse. I said they (the angles) looks like 45 degrees, rather than 60 degrees. And then it would be a square...... You are autist, fucking scumbag.

>>710369861
Hello, first time on the internet ? Welcome !
284
only the first two tiers are triangles, the rest are squares due to the angles of the wood stand
Why would they build a triangular frame in a square garden?

>>710370831
I dont know what yall are going on about, but this is clearly a 3 sided pyramid. angles should add to 180. 180/3 = 60 degree angles.
>>710362889
Enough
>>710371236
A tetrahedron actually. And its not particularly clear at all.
At least 12
>>710370850
>realizes how retarded he is, tries to normalize it by assuming people should have known he was retarded from the getgo
Hell, first time attempting Geometry? Welcome!
>>710371236
Yes, but the angles aren't 60 degrees
It has the shape of a four sided pyramid
>>710365736
faggot
Assuming it is a tetrahedron (triangle pyramid) and not hollow, we can see that the number of balls along one length (n) is 9. So the number of balls in the bottom layer is:
n(n+1)/2
or 9(9+1)/2
= 45
And the number of balls in the tetrahedron is:
n(n+1)(n+2)/6
or 9(9+1)(9+2)/6.
= 165
Maths fo' yo' ass!
>>710370831
Idiot, you don't calculate perspective, you have to find it with lines, like this. More or less precise, can't do it better, But no fucking way it is a square.
>>710371236
Nope, is square, there are no fucking 60 degrees cutting or corners.
Check just the front bottom 4 balls. If it was a 3 sided base the side balls would be touching at the back.
Besides im not sure that the balls would even stack neatly with a 3 sided base.
>>710371531
well the base of it is not square, and I can't say i know the math behind the perspective shit earlier but those angles are far bellow 90 degrees.
We can agree that there is 3 balls on the second to highest tier correct? if that's the case. it's 3 sided.
>>710371713
You didn't take into account that the house might be a triangle
>>710371784
>We can agree that there is 3 balls on the second to highest tier correct?
Nah
its simple 9+8+7+6+5+4+3+2+1+8+7+6+5+4+3+2+1+7+6+5+4+3+2+1+6+5+4+3+2+1+5+4+3+2+1+4+3+2+1+3+2+1+2+1+1
>>710371713
Theres no way to find the dimension of the rear wall as its to see whether the front we are staring at also is how the rear side appears. However, theres no way the stucture could stand if it was in fact flat on the backside (or a triangle as some called it) simply because a straight up and down wall of balls would fail in this case.
>>710372073
the back wall must extend just as the side we are looking at does so id imagine its a square with 4 edges the 4th being identical to the one we see in the foreground of the photo except on the rear side.
>>710363193
why the hell would you say that anyways?
>>710371978
well assuming the left most side is perpendicular to the fence, then shouldn't the angle of the board on the right be parallel with the fence if it were a square base? it's not
>>710363095
>>710372290
CHINA
>>710363182
Were assuming there's a layer we can't see?
>>710372428
you read my mind buddy
>>710372034
That's one face bruh
>>710372291
Yeah it is. You are missing the second perspective point. There is one either side of the focal point
>>710371978
The two visible balls in the back are touching, so yes, there's probably three balls there in total on that layer
>>710372535
Thank you, I was about to go into paint to do this myself. 3 sided confirmed. 165
>>710372535
>touching
If it were 3 they would be interlocking
>>710372535
Gay
>>710372535
>>710372623
They are not touching there is a 4th ball obscured from view. All 4 balls come close to touching in the center point but no they do not.
>>710362889
a lot.
>>710371056
No, it isn't.
You're dumb as fuck.
The answer is 165.
>+1
>+3
>+9
The third one is supposed to be +6.
>>710362889
1x1 = 1
2x2 = 4
3x3 = 9
4x4 = 16
5x5 = 25
6x6 = 36
7x7 = 49
8x8 = 64
9x9 = +81
Total = 285
>>710372768
I know what you're saying, but those are clearly touching. if there were a gap, I would be inclined to agree with you.
>>710363879
>assuming it is a triangular pyramid
>triangular pyramid
>pyramid
Pyramid: noun, a monumental structure with a square or triangular base and sloping sides that meet in a point at the top
>>710372878
lol
>>710372905
incorrect if there was only three balls the rear wall would be a straight up and down flat wall which could not stand given the objects in question.
>>710372768
The two balls in the back are way too close (see picture) for there to be four balls with the same distance to each other. Of course it doesn't rule out the possibility of something like pic related.
>>710372878
3 sided bro.
its
1
3
7
and so on
>>710373023
you mistakenly assumed the purple and green are touching in that photo.. none of the 4 touch bringing the blue close together
>>710373023
they only touch on their sides never in the center. But are tight enough to hold the ball above them
>>710372722
What are you talking about? From above, the second layer probably looks like pic related.
>>710373158
This. this is what's happening
>>710373209
incorrect see >>710372972
>>710373077

>>710362880.
0. Those are billiard balls.
>>710373292
No they do not, you are assuming the balls are as wide behind the ball that obsucres them as the ones in the foreground. There is a small gap between them behind the obscuring ball. This is common sense.

First of all, update your definitions.
Also,
>referring to the textbook definition of something to argue with someone over what a word means
you must have been the creative one in school.
t. Chemist, PF_5 is trigonal bipyramidal.
>>710372878
Course This calculation is from the top to bottom. With the agreed upon four sided pyramid.
There is too much space in relation to the diagonal of the bowling balls at the 2x2 bowling ball segment to support the single ball at the top. Therefore it must be 2x2 instead of the alternate thought process of there only being 3 balls in this segment.
Its not a triangle like you illuminigger fags think it is, its a diamond like my dick in a ylyl thread
>>710373396
/thread this photo is correct.
1.9 + 2.8 + 3.7 + 4.6 + 5.5 + 6.4 + 7.3 + 8.2 + 9.1 = 165

>>710373928
I see it now. The rear (and hidden) side actually starts at a higher elevation than the rest of the pyramid! Holy fuck, figured it out!
>>710362889
Need to see hidden side
Each level has :
1+2+3+4+5+6+7+8+9=45
1+2+3+4+5+6+7+8=36
1+2+3+4+5+6+7=28

1+2+3+4+5=15

>>710362889
Real question we should be asking our selves is why they have that many bowling balls?
Did the person lose control of their lives and dedicate it to a bowling ball god?
>>710374509
The base is 3 sided. 4 sided defenders are mongoloids
>>710362889
ZERO- none of them are bowling balls.
>>710362889
Calculate for volume of a pyramid
1/3 * base area * height
1/3(90)=30*9
270 balls
>>710373584
But you conveniently ignored the angle for the corner closest to the camera...
>>710375363
its 60 degrees
>>710375503
>>710375539
That was my point, but the guy I replied to didn't seem to get it. He was saying it's a diamond.
>>710365568
>>710365631
>they are 45 degree angles, more or less
Nigger those ate obtuse angles... Those are more like 120 degrees...
>>710365568
lol squares have 90 degree angles
ANSWER IS 165
there are 9 levels of bowling balls and each level is the level number times itself with the level numbers ascending as they go from top down.
1x4x9x16x25x36x49x64x81
=
285
this is assuming that there are bowling balls behind the ones we see, making a full 4 sides pyramid with bowling balls inside the pyramid.
However, if the the bowling balls that we as see are the only bowling balls that are there then there are only 81 bowling balls
>>710375964
it's 3 sided bro. try again

http://www.had2know.com/academics/pyramid-of-balls-height-calculator.html
>>710375539
You are ignoring the obvious pincushion distortion from a cheap digital camera cranked back to maximum wide angle.
Its 90 degrees. But the subtlety of photo interpretation is obviously lost one some who can only see the literalism of a poor photo
>>710375964
>4 sides
All that math but can't count to 3
>>710376114
lol, you serious nigga? 3 sided
>>710371774
That's where you're backwards, a 3 sided base would be much more stable and neat that a 4 sided base when stacking spheres
>>710375884
Look again, very close. I talk about the cuttings... they are like 45 degrees, and two of them makes 90 degrees....... got it??
165
I'm off to watch some porn now, fuck this shit
>>710362889
there are probably millions of bowling balls anon. There are probably factories that just make bowling balls.
>>710376433
both angles are >90*
>>710376657
...in China.
The real question is how many bowling balls they manage to fit into those 3 sided shipping containers.
This?
>>710373928
Nobody gives a fuck about your wood god and his wood angels.
>>710377033
added one too many layers
>>710376985
Of course they are. 45 one cut, and 45 other cut makes 90 degrees in total.
>>710377033
7th has 6 balls
so it's wrong
http://www.had2know.com/academics/pyramid-of-balls-height-calculator.html
Triangle base, 165 balls
>>710377159
I count 9?
>>710377246
On the perimeter, 1 ball should fit in the middle
>>710377472
my bad
>>710363472
Congrats someone can add
>>710377341
odd, but just check out the bottom layer
it's 9 across correct?
then the math is
9+8+7+6+5+4+3+2+1 = 45
45 balls at the bottom teir
>>710377033
also 7th layer has 6 balls not 7, something is wonky with the math here
>>710363472
I can confirm this
Every layer is just the one above plus how ever many more is needed to add a full row to (for this well say the bottom).
So the patters is 1 add the amount you need to make a full row below it, you get 3. Repeat this process until you have number values for each row then add them all up. In this picture there is 9 rows, assuming the stack is not hollow you get 1+3+6+10+15+21+28+36+45=165
well the bottom row is 9 and it goes up to 1, so...
9*9 =81
8*8=64
7*7=49
6*6=36
5*5=25
4*4=16
3*3=9
2*2=4
and the one on top
so 285?
more than 2
>>710377896
incorrect, here
>>710377621
I did my math by corner.
Total corner balls+total balls between by number of faces so (3x7)+3 then do this for ever other layer above and add them together that should account for the volume perfectly, presuming the balls are balanced in 1/2s not 1/3s
>>710378009
scratch that, i just realized it has a triangular base, not a square one.
for some reason i thought it had a square base
>>710378261
Ah, I see the error now
>>710378261
math goes like this
layer 1 = 1
layer 2 = 1+2 = 3
layer 3 = 1+2+3 = 6
layer 4 = 1+2+3+4 = 10
and so on.
