Rectangular Prism (Box) Volume Calculator
Calculate the volume of any rectangular box from its length, width, and height. The most common 3D shape calculation used in shipping, storage, construction, and aquarium sizing.
Formula
Volume = Length × Width × Height. All three dimensions are multiplied. The result is in cubic units of whatever measure you input.
Worked example
8 × 5 × 4: volume = 160 cubic units. An aquarium at 100 cm × 40 cm × 50 cm = 200,000 cm³ = 200 liters.
Practical guidance
Converting between volume units
Common conversions: 1 m³ = 1,000 L. 1 L = 1,000 cm³. 1 ft³ = 28.3 L. After calculating the box volume, use a volume converter if you need the result in different units like liters or gallons.
Packing efficiency
If you are packing items into a box, the usable volume is less than the total due to shape constraints. Spherical objects leave ~26% empty space even in optimal packing. Irregular shapes waste more. Use the calculated volume as an upper bound.
