there's at least 10

a decent amount

More than 2.

A whole damn stack of em

165

Impossible to tell but quite a lot

45+36+28+21+15+10+6+3+1
165

9x9^9 / 3

A plethora

81
In view, obscuring what could be something what is not bowling balls behind and inside.

lots

165 is the correct answers. The easiest way to calculate it is to use the binomial coefficient representation of the tetrahedral numbers. A tetrahedral number with a base edge length of n is calculated as (n+2 choose 3). So we have (9 choose 3)=165.

Shit I fucked up. It would be (11 choose 3) = 165.

Far too many to get in my ass.... but I'd try.

At least 2.

( x = x +1 ) ^2 * 9

285?

361 niggers

...

9 width
so
9*9+8*8+7*7+6*6+5*5+4*4+3*3+2*2+1= 285

the correct answer is 165. Easiest way to get the answer without being a fucking mathematician is to find the number of balls in the bottom row. After that just subtract how many balls are in the longest row from the stack below it then add them all together. Example: Bottom row has 45 balls,subtract 9(amount of balls in the longest row) which leaves you with 36,the amount of balls in the second to bottom row.

this

That would be for a square,ya dingus

Thats what I got aswell. I read engineering math recently but not sure if i fucked up kek

262

well i presume it's a square pyramid, it could be a triangle, but i forgot how to calculate that.

n^2 + n

You failed

81. i win

i counted all the balls
no joke

1- 1
2- 3
3- 6
4- 10
5- 15
6- 21
7- 28
8- 36
9- 45

total is 165

165

honest question, how do you calculate this.

pascals triangle, or the equation for a triangular based pyramid

0. Those aren't bowling balls, they're alien eggs. We're all gonna die...

square pyramidal number for a square and tetrahedral number for triangular. you can easily find the answer on google with just knowing how many stacks of balls there are.

>pascals triangle
thanks

Refer to

about three fiddy

On the assumption it is individual layers form the ascending triangular numbers ranging from T1 to T9, if we take the sum of these numbers from 1 to 9 using the following summation formula (which can be proved by induction):
n(n+1)(n+2)/6
substitute n = 9
9(10)(11)/6
This gives 165.
