Which term describes the space in three dimensions, often expressed in cubic units?

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

Answer: (D)

Volume describes the space inside a three-dimensional object and is measured in cubic units. This term captures how much space an object occupies in all three directions (length, width, and height). For example, a cube with side length s has volume s × s × s = s^3, so its units are cubic (like cubic centimeters or cubic meters). The other terms don’t fit for describing 3D space: power relates to exponents, radical to roots, and width is only a linear measurement in one dimension.
