Question

The floor of a cargo truck is 22 1/2 square feet. What is the volume of the storage space in cubic feet if the truck is 7 1/5 feet high? Show, label, and explain your work.

Answer 1

162 ft^3

Explanation:

volume = area of base * height

V = 22 1/2 ft^2 * 7 1/5 ft

Change the mixed numerals into fractions.

V = 45/2 ft^2 * 36/5 ft

Multiply the fractions.

V = 45/2 * 36/5 ft^3

Switch the denominators.

V = 45/5 * 36/2 ft^3

Simplify each fraction.

V = 9 * 18 ft^3

V = 162 ft^3
