What does volume measure?

Volume measures the amount of space an object occupies. It is a fundamental concept in physical science that defines three-dimensional space. When we talk about the volume of an object—be it a liquid, solid, or gas—we are referring to the extent of three-dimensional space that it fills.

This measurement can be quantified in various units such as liters, cubic centimeters, or gallons, depending on the context and the substance being measured. For example, if you fill a container with water, the volume of the water is determined by how much space it occupies within that container, regardless of the water's mass or weight. Understanding volume is essential in fields such as chemistry, physics, and engineering, where it often plays a critical role in calculations regarding density, buoyancy, and material properties.
