What are the standard units used to express volume in the context of the material?

• A. Cubic centimeters (cm³)
• B. Kilograms
• C. Liters
• D. Cubic meters (m³)

Answer: (A)

Volume for typical material samples is expressed in cubic centimeters because this size is convenient for solids and pairs well with common mass units. The reason this works so nicely is that 1 cubic centimeter equals 1 milliliter, so densities of materials are often reported in grams per cubic centimeter (g/cm^3), keeping numbers simple and directly related to mass measurements. For larger quantities or liquids, liters or cubic meters are used, but in material contexts—especially for small samples and lab data—cm^3 is the standard. Kilograms measure mass, not volume, and would not describe how much space a material occupies.
