Find volume of triangular pyramid or prism.

I hope this helps you

Yeah, it's a triangular pyramid.

:)

661.5 :)

Step-by-step explanation:

So we know the formula is 1/3*B*H, and the height is 15! That means we have to solve for b!

10.5 * 25.2 = 264.6 Now we divide 264.6/2 to get 132.3.

Now we can use the formula.

132.3 * 15 * 1/3 = 661.5 :)

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
