Volume — the amount of three-dimensional space occupied by an object — is one of the most fundamental measurements in mathematics, science, and everyday life. Whether you're filling a swimming pool, designing a building, or cooking a meal, understanding volume is essential.

What Is Volume?

Volume is a three-dimensional measurement expressed in cubic units (cm³, m³, in³, ft³, liters). It quantifies how much space an object occupies or how much a container can hold.

Volume Formulas for Common Shapes

Cube

V = s³

Where s is the side length.

Sphere

V = (4/3)πr³

Where r is the radius.

Cylinder

V = πr²h

Where r is the radius and h is the height.

Cone

V = (1/3)πr²h

A cone has one-third the volume of a cylinder with the same base and height.

Rectangular Prism

V = l × w × h

Where l, w, h are length, width, and height.

Unit Conversion

Common volume conversions: 1 m³ = 1000 L, 1 cm³ = 1 mL, 1 in³ = 16.387 cm³, 1 ft³ = 28.317 L.

Applications

Volume calculations are used in construction, cooking, shipping, manufacturing, medicine, and countless other fields.
