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
