Volume is the amount of three-dimensional space occupied by a body or enclosed within a container. It is measured in cubic units such as m³, cm³, in³, or ft³.

Which shapes can I calculate here?

This tool calculates the volume of common solids: cube, rectangular prism, cylinder, cone, sphere, pyramid, triangular prism, and torus.

Yes. Choose the base unit (m, cm, mm, in, ft). The formula is unit-agnostic: just make sure all inputs use the same unit.

Formula

V = l × w × h

Volume: recap

In solid geometry, volume measures the space a 3D object occupies. For regular solids, we have closed-form formulas; for irregular objects we normally have to integrate or approximate.

Most used formulas

Cube: \( V = a^3 \)
Rectangular prism: \( V = lwh \)
Cylinder: \( V = \pi r^2 h \)
Cone: \( V = \frac{1}{3} \pi r^2 h \)
Sphere: \( V = \frac{4}{3} \pi r^3 \)
Square pyramid: \( V = \frac{1}{3} b^2 h \)
Triangular prism: \( V = \frac{1}{2} b h_t \cdot L \)
Torus: \( V = 2 \pi^2 R r^2 \)

Units & conversions

1 dm³ = 1 L, 1 m³ = 1000 L, 1 US gallon ≈ 3.78541 L. So once you get the volume in cubic cm (cm³), divide by 1000 to get liters.
