So, /b/, how many bowling balls are there in this pyramid?

>>736696860
enough to break the ice

Pyramid has 4 sides m8

>>736697074
Should say "4 faces" but really 5 sides.

>>736697074
m4 has 8 Pyramid

But since that is a shit ton of balls then it's probably jut a façade.

No, it has not. This pic is for compairision (spelling?) of angles only, not for size.

>>736696860

9841

>>736696860
yes

>>736697627
Taken with a regular focal length lens

Ops pic was taken with an ultra wide angle lens which is messing with perspective.

It definately has 4 sides (plus its base ofc)

>>736696860
many

>>736697795

And you know this, because.......??

Bottom row has 9+8+7+6+5+4+3+2+1. The row above has the same sequence minus the longest row aka 8+7+6+5+4+3+2+1. The row above shorter still and so on.

Adding everything gives you this sequence of 9+2*8+3*7...+8*2+9*1.

Simplifies to 2(9+2*8+3*7+4*6)+5*5

=2(9+16+21+24) + 25

= 2(70) + 25 = 165

>>736697074
It's a Triangular Pyramid

>>736697944

It's a tetrahedron.

>>736697933
except its a squaracle pyramid

>>736697074
Yea OP is retarded this is a tetrahedron or the FOV is quake level on this shit.

>>736696860
its 9 to the 3rd power you fools, look at it. it exponetially increases with each row making it 729

>>736696860
Assuming it's completely solid
summation of the first 9 triangle numbers
1+3+6+10+15+21+28+36+45
=165

>>736697627

1785 in that one.

>>736696860
meh, /b/ needs a latex support...

sigma k=1, 9 over sigma 1, k

It's 9 factorial you idiot.

>>736697795
The corner of the house appears 90 degrees, and the corner of the "pyramid" does not match

>>736697627
How the fuck is he climbing that

>>736698113
If it's not solid, and it's just a hollow pyramid, it's the perimeter of each layer (assuming that the bottom face isn't actually filled in)
1+3+6+9+12+15+18+21+24=109

At least 16

>>736696860
Sum n = 0-8, (((9-n)^2)/2)

Too lazy to do the actual math.

>>736696860
Summation from 1 to 9 of n^2 = 285

about tree fiddy

>>736698788
That would be a square pyramid. This one is clearly triangular.

>>736697285
this is the only right answer. It's a solid pyramid for starts.

Secondly.... if you start by counting the bottom layer.

9+8+7+6+5+4+3+2+1=45
8+7+6+5+4+3=2+1=36
7+6+5+4+3+2+1=28
6+5+4+3+2+1=21
5+4+3+2+1=15
4+3+2+1=10
3+2+1=6
2+1=3
1
45+36+28+21+15+10+6+3+1=165

For any pyramid, the volume is 1/3(B*H) where B is the base area of the pyramid and H is the height. For an equilateral pyramid, B would be calculated as ((sqrt3)/4)*a^2 where a is the length of the sides. If a = 9, then the base area is about 35. Plugging that into the first equation we find that the equilateral pyramid has the volume of 105. Learn to do maths.

>>736697328
This

>>736699618
Wrong you stupid faggot.

>>736696860
None, until I see finger holes they are simply balls.

>>736696860

Its obvious. Only add the faces, because it was built by joseph to store grain. 109 bowling balls, the inside is 73 bushels of barley.

because the top one isn't a bowling ball

The corner of the pyramid is closer to the lens. This is how those lenses work.

Real estate photographers use them to make rooms look huge. The gaps between couches look larger than the couch but when you visit them you can barely fit through.

Its pure barrel distorion.

Ops pyramid is square and this is ancient bait

>>736696860
like 8?

>>736704243
But it's not.

Those are perfect 180 degree angles, for an equilateral triangular base. It's a fucking tetrahedron. If your claim were true there would be distortions on the ground and the balls would appear to be different sizes, when that's clearly not the case.

>>736698470
Physics. The balls are held together by the lip on the base, and the downward force of the weight of the other balls.

To people saying 285, it is a 3 sided pyramid. Not a 4 sided one ya ding dongs.

>>736704669
Don't argue. This is a classic troll thread where people intentionally say it's 4 sided when it is clearly not.

285 balls.

The area of the first triangle is 45, the next is 44, the next is 42, etc subtracting the next row down all the way to 9.

>>736699383
That's wrong. The pyramid is made up of layers of squares.

sum_x=1^9 x^2 = 1^2 + 2^2 + ... + 9^2 = 285

>>736704669
>distortions on the ground

Nah. Only linear features are distorted.


The level of distortion is relative to distance from the lens.

He would be standing at best a couple of feet from the front edge of the pyramid

>>736705246
>clearly

To a smilpleton who doesnt know anything about optics and takes everything at face value

Its square.

No troll.

>>736705246
I like to argue, anon.
>>736705448
The ground is a linear feature, idiot.

>>736705644
>ground is a linear feature

Nah.

Stay simple anon

Holy shit, the level of education on b i abysmal, none of you got it right, it's 175.
For jeebus sake, it's a simple math problem
each layer can be calculated as this
Xn = x + X n-1 Now calculate the series from 0 to 9.

3 or 4 people said 285.

If it was a triangular base then the 2 balls behind the front corner would be touching at the back.

They arent

Its square, just distorted.

You are all muppets

>>736706398
u will allways find 3 or 4 people who say someting similar. Just a question of how many u ask.
same as if you let a monkey type on the keyboard. the longer he types the more actual words you will find in the salad.

2 minutes is a free online website that corrects lens distortion. All default settings... loaded it in, saved the output.

If i could be bothered to launch photoshop i could make it look much better.... but meh.

215

It's 248 you cuckolds.

>>736708643
Cuckolds would say 50something because they only count the black ones

206 Balls approximately.

>>736710061
Was it right?

>>736696860
take "n" as the number of balls along the side of the base. The total number of balls is (1/6)[(n^3) +3(n^2) + 2n]

This pyramid has base side lengthof 9
(1/6)[((9)^3) +3((9)^2) + 2(9)] = 165 balls
>>736697627
For the square pyramid. Take "n" as the number of balls along the length of the base. The total number of balls is (1/6)[2(n^3) + 3(n^2) + n].

This square pyramid has base side length of 17
(1/6)[2((17)^3) + 3((17)^2) + (17)] = 1785 balls

Q.E.D.

>>736705365
layers of squares.
special kind of stupid?

>>736710793
Hang on if the first picture is distorted and it actually is a square base then just use the second equation and plug in 9. (Should get 285 balls) That's only if it really is distorted.

There are 9 layers.

> rectangles

>>736706826
You can tell by the angle cut into the boards that it's not a 90° angle, it's more like a triangle. Also, you can draw the rest of the bowling ball that is hidden to reveal they do indeed touch

>>736696860
hard to say because we dont see the bottom im assuming its two more rows .

>>736696860
Balls are touching.
I am impressed no one said this is gay.
/b/ is going down the drain.
