Volume Formulas for Common 3D Shapes
Understanding the formulas behind the calculations is helpful, even when using a free calculator.
Cube
Volume = Side³
Where “Side” is the length of any edge of the cube.
Example: A cube with a side length of 2 meters has a volume of 2³ = 8 m³.
Rectangular Prism (Cuboid)
Volume = Length × Width × Height
Example: A box with dimensions 3 m × 2 m × 1 m has a volume of 6 m³.
Cylinder
Volume = π × Radius² × Height
Example: A cylinder with a radius of 1.5 meters and height of 4 meters has a volume of π × 1.5² × 4 ≈ 28.27 m³.
Sphere
Volume = (4/3) × π × Radius³
Example: A sphere with a radius of 1 meter has a volume of (4/3) × π × 1³ ≈ 4.19 m³.
Cone
Volume = (1/3) × π × Radius² × Height
Example: A cone with a radius of 1 meter and height of 3 meters has a volume of (1/3) × π × 1² × 3 ≈ 3.14 m³.
Pyramid
Volume = (1/3) × Base Area × Height
Example: A pyramid with a base area of 9 m² and height of 4 meters has a volume of (1/3) × 9 × 4 = 12 m³.
Prism
Volume = Base Area × Height
Example: A triangular prism with a base area of 5 m² and height of 6 meters has a volume of 5 × 6 = 30 m³.
