So, Sup Forums, how many bowling balls are there in this pyramid?

So, Sup Forums, how many bowling balls are there in this pyramid?

enough to break the ice

285

144

Pyramid has 4 sides m8

Should say "4 faces" but really 5 sides.

m4 has 8 Pyramid

>he thinks the creator is dumb enough to waste actual bowling balls on the inside

seven

165

>really 4 Should say but sides 5 faces

243

285

Assuming that it is a solid block 258
But since that is a shit ton of balls then it's probably jut a façade.

45+36+38
119

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

9841

yes

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)

many

>pic was taken with an ultra wide angle lens

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

285

165

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

It's a Triangular Pyramid

It's a tetrahedron.

except its a squaracle pyramid

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

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

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

1785 in that one.

meh, Sup Forums needs a latex support...

sigma k=1, 9 over sigma 1, k

165

It's 9 factorial you idiot.

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

How the fuck is he climbing that

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

Your mom's ass

root@localhost> perl -e "for($i=1;$i

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

Too lazy to do the actual math.

Summation from 1 to 9 of n^2 = 285

about tree fiddy

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

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.

This

Wrong you stupid faggot.

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

3 obviously you dumbass

...

Wrong, you stupid faggot.

165

...

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.

164...

because the top one isn't a bowling ball

it's the earth

A million and 2.

282

420

count them yourself faggot

please let it be 404 bballs soon

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

like 8?

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.

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.

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.

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

>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

>clearly

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

Its square.

No troll.

I like to argue, user.
The ground is a linear feature, idiot.

>ground is a linear feature

Nah.

Stay simple user

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.

275

3 or 4 people said 285.

Seems about right. 275 or 285 seems really high

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

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.

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

206 Balls approximately.

Was it right?

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
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.

layers of squares.
special kind of stupid?

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.

Any user who's going to get a calculate has no life

At least seventeen

is it a pyramid or a tetrahedron /thread

Tree fiddy.

165
There are 9 layers.
Layer n contains 1 + 2 +... + n = n(n+1)/2

> rectangles

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

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

Balls are touching.
I am impressed no one said this is gay.
Sup Forums is going down the drain.
