About volume
Volume is the space inside a solid, in cubic units (m³, cm³) or litres. You always need three dimensions (e.g. radius and height).
Split a complex solid into simple shapes; find each volume and add.
Volume formulas
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 one unit for all dimensions; convert first if needed.
Sample results
Cube: a=4 → V=64 cm³.
Cylinder: r=2, h=7 → V≈87.96 cm³.
Sphere: r=5 → V≈523.6 cm³.
Pyramid: base 4×4, h=9 → V=48 cm³.
