Calculate the volume of a rectangular prism, also called a cuboid or box, from its length, width and height. The volume equals length times width times height, so a box that is 5 by 4 by 3 holds 60 cubic units. This calculator also returns the total surface area, computed as two times the sum of the three face pairs, and the space diagonal that runs from one corner to the far opposite corner. Rectangular prisms describe shipping cartons, aquariums, rooms, bricks and shelving, so a fast volume answer helps with capacity, shipping weight estimates and material planning. Enter the three dimensions in a consistent unit and the volume comes back in that unit cubed while the surface area is in the unit squared. All arithmetic runs locally in your browser at full precision with nothing sent to a server, and the volume copies with a single click for quick reuse.
Multiply length by width by height, so a 2 by 3 by 4 box has a volume of 24.
Yes. A rectangular prism, cuboid and box all mean a six-faced shape with rectangular sides.
It sums the areas of all six rectangular faces, twice each of length by width, width by height and length by height.
