Formula

volume = length x width x height

Multiply the three perpendicular dimensions to get cubic space.

This works for box-shaped solids.

Example

10 units, 6 units, 4 units gives Volume 240.

Check

Mixing units or scales across length, width, height before calculating volume.
Rounding too early when the volume still feeds another step.
