Volume is equal to which product of dimensions?

• A. Height x Length x Width
• B. Length x Width
• C. Mass x Density
• D. Volume x Height

Answer: (A)

Volume tells us how much space something occupies in three dimensions. For a rectangular solid, that space comes from multiplying its three linear dimensions: height, length, and width. The order doesn’t matter, but you do need all three factors. Length times width gives the base area, not the volume, so you’d still need height to get volume. Mass times density isn’t volume either—density relates mass to volume (volume = mass/density), so multiplying them isn’t the right formula. And volume multiplied by height would yield a quantity with no standard interpretation in this context. Therefore, height × length × width is the correct way to find volume.
