Volume is typically expressed in which units?

• A. Cubic feet or cubic yards
• B. Cubic inches
• C. Liters
• D. Square feet

Answer: (A)

Volume is the amount of space a three‑dimensional object or room occupies, so it must be expressed in cubic units. In real estate and construction, the standard way to measure space like rooms or buildings is in cubic feet or cubic yards because they reflect three-dimensional extent (feet raised to the third power, or yards cubed). Metric liters do appear for liquids or smaller-scale measures, but in US real estate contexts cubic feet or cubic yards are the go‑to units. Cubic inches exist for tiny objects, but they’re impractical for large spaces, and square feet measures area, not volume. So the best option is cubic feet or cubic yards.
