How many cubic feet are in one cubic yard?

• A. 12
• B. 27
• C. 36
• D. 48

Answer: (B)

Volume changes with the cube of a linear measurement, so you convert each dimension and multiply. One yard is 3 feet long, so 1 cubic yard equals 3 ft × 3 ft × 3 ft, which is 27 cubic feet. The other numbers don’t come from cubing the 3-foot conversion, since they don’t represent the product of three 3-foot dimensions.
