Frequently Asked Questions

How do I calculate the volume of a cube?

Volume = side cubed. For sides of 4cm: volume = 64 cubic centimetres.

What is the formula for the volume of a sphere?

Volume = (4/3) x pi x radius cubed. For radius 3: volume = 113.1 cubic units.

How do I calculate the volume of a cylinder?

Volume = pi x radius squared x height. For radius 5 and height 10: volume = 785.4 cubic units.

What is the formula for the volume of a cone?

Volume = (1/3) x pi x radius squared x height. A cone has one third the volume of a cylinder with the same dimensions.

How do I convert litres to cubic metres?

1 litre = 0.001 cubic metres. Divide litres by 1000 to get cubic metres.

What is the volume of a pyramid?

Volume = (1/3) x base area x height. For a 6x6 base and height 9: volume = 108 cubic units.

How do I calculate the volume of an irregular shape?

Use water displacement or decompose into standard shapes and sum the volumes.

What units should I use for volume calculations?

Always use consistent units. Centimetre inputs give cubic centimetre results.
