Question

The base of a pyramid is a rectangle whose base and height are 9m and 4m. The volume is 120. What is the height? (plz give description on how to find the answer, if you can)

Answer 1

10 m.

Explanation:

Volume of a pyramid is

V = 1/3Bh B = area of base h = height of pyramid

The base is a rectangle, so B = lw = 9(4) = 36

120 = 1/3(36)h = 12h

h = 10 m
