The volume of a square pyramid is 72 inches square if the dimensions of the square are 6in by 6in what is the height of the pyramid

Work Shown:

A = area of pyramid base = 6*6 = 36 square inches

h = unknown height

V = volume of pyramid

V = 72 given info

V = (1/3)*A*h ... pyramid formula

72 = (1/3)*36*h

72 = 12h

12h = 72

h = 72/12

h = 6

9 inches taller!

Explanation:

so with 5'8, i made it go all the way to 5'0. So you have 8 inches taller. then go to 5'0 to 4'11, which is 1 inch lower. 8 + 1 = 9, so it's 9 inches taller.  :)
