How many cubic meters are in one cubic foot?

• A. 0.093 cubic meters
• B. 0.028 cubic meters
• C. 0.405 cubic meters
• D. 0.836 cubic meters

Answer: (B)

Converting cubic units uses the cube of the length conversion factor. One foot equals exactly 0.3048 meters, so the volume in cubic meters is (0.3048 m)^3. Calculating gives 0.3048^3 ≈ 0.0283168 m^3, so one cubic foot is about 0.0283 cubic meters. Rounding to three decimals gives 0.028 cubic meters, matching the correct choice.

The other numbers would come from using the square of the conversion factor instead of the cube (0.3048^2 ≈ 0.093), which would describe square meters per square foot, not cubic meters per cubic foot, or from misplacing the exponent, so they don’t reflect the actual volume conversion.
