Which term corresponds to the amount of space occupied in three dimensions, expressed in cubic units?

• A. Power
• B. Radical
• C. Width
• D. Volume

Answer: (D)

The concept being tested is how we measure the amount of space inside a three‑dimensional object. That measure is called volume, and it’s expressed in cubic units because it comes from multiplying three lengths together: length, width, and height. For a rectangular prism, volume is found by length × width × height, and the units multiply to cm × cm × cm, giving cubic centimeters. This really captures the total space the object can hold, unlike width, which is just one dimension and doesn’t account for depth, or terms like power and radical, which are about exponents and roots rather than volume.
