Which statement defines Volume as a product of dimensions?

• A. Volume equals Height x Length x Width
• B. Volume equals Length x Width
• C. Volume equals Mass x Density
• D. Volume is measured in liters

Answer: (A)

Volume is the amount of space inside a three-dimensional object, and for a rectangular solid it's found by multiplying its three dimensions. Height × Length × Width gives that product, yielding a measure in cubic units, which is why this statement defines volume as a product of dimensions. The other ideas aren’t the definition: Length × Width gives area, not volume. Mass × Density relates volume through a separate formula (volume = mass ÷ density) rather than a direct product of dimensions. And saying volume is measured in liters describes a unit, not how volume is calculated. For example, a box 5 by 4 by 3 has volume 5×4×3 = 60 cubic units (60 mL if the measurements are in centimeters).
