Volume has which unit?

Volume has which unit?

• A. cm^3
• B. L
• C. m^3
• D. cm^2

Answer: (A)

Volume is measured in cubic units because it describes how much space something occupies in three dimensions. A cubic centimeter (cm^3) is a classic unit of volume since it’s derived by cubing a length unit (a centimeter across by a centimeter by a centimeter). Another valid volume unit is the liter, and a liter equals 1000 cubic centimeters, while a cubic meter equals 1,000,000 cubic centimeters. But cm^2 is not a volume unit—squaring a length gives area, not volume. In many practical contexts, especially for small objects or in imaging, volume is expressed in cm^3 (equivalently in mL), so cm^3 is the best fit among the options.
