1 cubic yard equals how many cubic feet?

• A. 9
• B. 18
• C. 27
• D. 36

Answer: (C)

When converting volume, apply the linear conversion to each dimension and multiply. A yard is 3 feet, so a cubic yard is 3 ft by 3 ft by 3 ft, which equals 27 cubic feet. In other words, 1 yd³ = (1 yd)³ = (3 ft)³ = 27 ft³. The number 9 would reflect area (3 ft × 3 ft) rather than volume, while 18 and 36 don’t come from cubing the 3-foot conversion, so they don’t represent a full cubic-yard to cubic-feet conversion.
