Question

Find the height of a square pyramid that has a volume of 75 cubic feet and a base length of 5 feet.

Answer 1

volume of the pyramid = (1/3) x Area of the base x Height (1)

As the base length = 5 feet

So Area of the base = 5 x 5 = 25 square feet

While volume of the pyramid = 75 cubic feet

Putting values in equation (1);

75 = (1/3) x 25 x Height

Height = (75 x 3) / 25

Your height = 9 feet

Answer 2

Volume = 1/3 * area of the base * height

75 = 1/3 * 5^2 * h

h = 75 * 3 / 25 = 3*3 = 9 feet answer
