If the area in square feet is 0.875 and the length is 75 feet, what is the volume in cubic feet?

• A. 60.0 cubic feet
• B. 65.625 cubic feet
• C. 70.0 cubic feet
• D. 75.0 cubic feet

Answer: (B)

Volume is found by multiplying the base area by the height for a rectangular prism. With a base area of 0.875 square feet and a length (height) of 75 feet, the volume is 0.875 × 75 = 65.625 cubic feet. This uses the fact that square feet times feet gives cubic feet, and 65.625 ft^3 is the exact result.
