About volume
Volume is how much space a 3D shape holds, in cubic units (m³, cm³) or litres. You need the right dimensions (e.g. radius and height).
For a compound shape, split it into simpler parts, work out each volume and add them.
Volume formulae
Cube: V = a³
Cuboid: V = L × w × h
Cylinder: V = πr²h
Sphere: V = (4/3)πr³
Cone: V = (1/3)πr²h
Pyramid: V = (1/3) × base area × h
Units
- 1 m³ = 1,000 L.
- 1 m³ = 1,000,000 cm³.
- 1 L = 1 dm³.
- 1 cm³ = 1 mL.
- Use the same unit for every dimension; convert beforehand if necessary.
Example results
Cube: a=5 → V=125 cm³.
Cylinder: r=3, h=4 → V≈113.1 cm³.
Sphere: r=4 → V≈268.1 cm³.
Pyramid: base 3×3, h=6 → V=18 cm³.
