Question

A driveway is 81 feet long, 12 feet wide, and LaTeX: \frac{1}{2}1 2 feet deep. How many cubic feet of concrete will be required for the driveway? (This is a volume question)

Group of answer choices

A.458 cubic feet

B.423 cubic feet

C.5,832 cubic feet

D.486 cubic feet

Answer 1

D

Explanation:

Volume = length × width × height

= 81 × 12 × ½

= 486 ft³

Answer 2

V =486 ft^3

Explanation:

We will assume that the driveway is rectangular

V = l*w*h where l is the length, w is the width and h is the height

V = 81 * 12* 1/2

V =486 ft^3
