For example, if the two sides of the base are of length 3 inches and 6 inches respectively, and the height of the box is 2 inches, then using the box volume equation results in 3 x 6 x 2 = 18 x 2 = 36 in 3 (cubic inches).Īlternatively, the area of one side of a box might be given, and the height relative to that side. Three measurements need to be known to compute the volume of any box with a rectangular shape: the lengths of two sides of its base, as well as the height. If that is what you are calculating and want to know what it can hold, make sure to measure its internal, not external dimensions, otherwise you will need to then subtract the volume of the walls.Įxample: find the volume of a rectangular box However, in practical situations we usually talk about the volume in terms of the space enclosed by the box or tank, and that is what the calculator above calculates. It should be noted that "volume of a box" may not be a precise term, since if we take the box to be an abstract mathematical concept, its walls have zero thickness and the box itself has zero volume. That is fairly easy to do in your mind if the numbers are small, but quickly gets inconvenient if the numbers become large, where a volume of a box calculator such as the above gets really useful. In practical situations, you might have a plan or engineering schematic in which the measurements are all given making your task significantly easier. To find the volume of a rectangular box or tank, you need to take three measurements, then multiply them.
If the length was in feet, the result will be in cubic feet, and so on for yards 3, miles 3, mm 3, cm 3, meters 3. If you measured the lengths in inches, the result will be in cubic inches. Make sure to have all measurements in the same unit, if you are doing the math by hand, and if using our calculator - make sure to select the appropriate metric. The result from the calculation, using our volume of a rectangular box calculator or otherwise, will always be in the length unit used, cubed. Measuring the sides of a rectangular box or tank is easy. The formula is then volume box = width x length x height. The volume of a rectangular box can be calculated if you know its three dimensions: width, length and height.
