Question

What’s the length of a box with a volume of 720 cubic inches, a width of 15 inches, and a height of 4 inches? (Hint: Isolate the length (L) on one side of the formula V = LWH.)

Answer 1

The box is 12 inches long.

Explanation:

Box volume = height * width * length. In this problem we want the length, so we solve the given equation for length:

720 in^3

length = -------------------- = 12 in

(15 in)(4 in)

The box is 12 inches long.

Answer 2

Box volume = height * width * length. In this problem we want the length, so we solve the given equation for length:

720 in^3

length = -------------------- = 12 in

(15 in)(4 in)

The box is 12 inches long.
