Calculate the volume of a box, sphere, cylinder or cone from its dimensions.
How the volume calculator works
Pick a shape and enter its dimensions, and this calculator returns the volume. It covers the four most common solids used in school and everyday projects.
For landscape materials in cubic yards, see the dedicated cubic yards calculator.
Using the calculator
- Choose the shape.
- Enter the required dimensions.
- Read the volume.
The formula
box = l×w×h · sphere = ⁴⁄₃πr³
cylinder = πr²h · cone = ⅓πr²h
The default scenario, worked through
Worked through, a shape of Box / cuboid, radius of 3, height of 5 produces a volume of 24. Change any field and every figure updates as you type.
Common questions
How do I calculate volume?
It depends on the shape — multiply the relevant dimensions using the shape’s formula. This tool applies the right one automatically.
What units does it use?
Whatever units you enter — the result is in those cubic units. Keep all dimensions in the same unit.
What’s the volume of a cone vs a cylinder?
A cone is exactly one third of a cylinder with the same base and height.
