Calculate Liters in a Box

Calculator how many liters fit in a box of a certain size or what size the box needs to be.

Mathematically, a box (carton, crate) is a cuboid. The size of the box is precisely determined by specifying the length, width and height, the volume results from the product of these three values, i.e. length times width times height. Of course, the legths inside the box have to be measured here if the box wall has a notable thickness. Or you can measure on the outside and subtract the single (if one side is open) or double (if the sides are closed) thickness.

Example: a box that is 30 cm long, 10 cm wide and 20 cm high has a capacity of 6 liters.

Please enter any three values. This can be the length, width and height of the box, or two of these values and the volume. The fourth value will be calculated.

Without the lid, this wooden box has internal dimensions of 21.4 cm x 18.7 cm x 4.8 cm, the lid is 1.4 cm high, so it can hold a maximum of almost 2.5 liters (21.4 x 18.7 x 6.2 / 1000). Not if it's filled with a liquid though, which will spill out when you open the lid (and this box wouldn't be watertight anyway).
