Geometry formulas
Each result is calculated from the dimensions entered using standard Euclidean geometry formulas. The tool checks required constraints such as the triangle inequality and positive lengths.
Unless a unit is explicitly selected, lengths use any consistent unit, areas use its square, and volumes use its cube.
Questions
Volume Calculator FAQ
What units does a volume result use?
Volume uses cubic units. Dimensions entered in centimeters produce cubic centimeters, for example.
How is cylinder volume calculated?
Multiply pi by radius squared and then by cylinder height.
