How to use the Volume Calculator
Choose the solid so the inputs can be interpreted correctly. For a box, enter length, width and height. Cylinders and cones use radius and perpendicular height; spheres need only radius. Volume uses the cube of a length unit, such as cubic meters or cubic inches, so it is essential that every input uses the same unit.
The calculation
Worked example
A box with lengths 3, 4 and 5 has volume 60 cubic units. A cylinder with radius 2 and height 3 has volume 12π, approximately 37.6991 cubic units.
Assumptions and limits
These formulas describe ideal solid shapes and do not automatically subtract wall thickness, openings or internal voids. A tank’s usable capacity may differ from its external geometric volume. A cone’s slant height is not its perpendicular height. The answer is rounded for display and is not a materials or structural specification.
Common questions
Can I enter diameter instead of radius?
Divide the diameter by two before entering it as radius.
Does a box’s orientation matter?
No. Multiplying the same three perpendicular dimensions gives the same volume regardless of which is named length, width or height.
