Question

An above-ground rainwater tank is rectangular and has a length of 15

feet and a height of 2 feet. It will hold 375 cubic feet of water. What is the

height of the rainwater tank?

Answer 1

The width of the tank is 12.5 feet

Explanation:

We need to find the width, not height of the rainwater tank, since the height is already given.

The volume of a rectangular prism is given as:

V = L * W * H

where L = length of the tank

W = width of tank

H = height of tank

We have its volume as 375 cubic feet and the length, L, as 15 feet and height, H, as 2 feet.

Therefore, its width is:

375 = 15 * W * 2

375 = 30W

=> W = 375 / 30

W = 12.5 feet

The width of the tank is 12.5 feet.
