Box volume calculator: volume of a rectangular box in litres or cubic units, plus its surface area.
V = l · w · h
How to use this calculator
- Choose the quantity you want under “Solve for”.
- Type the known values and pick their units: any combination works.
- The result updates as you type. Open “Show the steps” to see the substitution.
V = length × width × height. 1 000 cm³ = 1 L and 1 m³ = 1 000 L.
Useful for moving boxes, aquariums, shipping and storage.
Formula
V = l · w · h
