What does volume refer to in geometry?

Volume in geometry specifically refers to the amount of space occupied by a three-dimensional figure. This measurement allows us to understand the capacity of a solid object, such as how much liquid it can hold or how much material is needed to fill it.

To determine the volume of various three-dimensional shapes, specific formulas are used, such as length × width × height for a rectangular prism or (1/3) × base area × height for a cone. Understanding volume is crucial in many fields, including engineering, architecture, and everyday problem-solving where space and capacity are considerations.

The other options do not correctly define volume. A two-dimensional figure does not have volume, the sum of edges is a measure of the perimeter or edge length, and surface area refers to the total area covering a solid object, none of which capture the essence of volume.
