The Mass or Weight of a Solid Cuboid formula provides the weight or mass of a cuboid (a.k.a. box, right parallelepiped ) of length (l), height (h) and depth (d) and a mean density (mD).
INSTRUCTIONS: Choose units and enter the following:
- (l) Length
- (h) Height
- (d) Depth
- (mD) Mean Density.
Cuboid Mass (M): The calculator returns the mass in kilograms. However this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The Mass or Weight of a cuboid or rectangular container formula computes the volume of rectangular geometric shape based on the input parameters. With the volume of the cuboid, this formula then executes the simple equation below to compute the approximate mass of the object.
`M = mD * L * D * H`
where:
- M = Mass of the Object
- mD = Mean Density of the Object
- L = Length of the cuboid
- W = Width of the cuboid
- H = Height of the cuboid
The mean density (mD) of many common substances, elements, liquids and materials can be found by clicking HERE(e.g. the `mu_(density) (water)` is 1000.0 kg/m³).

Mean density is scientifically volume divided by mass. There are various unit for density adopted by cultures and industries. Common units for density included the following:
- kilograms per cubic meter (kg/m3)
- grams per cubic centimeter (g/cm3)
- grams per liter (g/L)
- pounds per cubic feet (lb/ft3)
- ounces per cubic inch (oz/in3)
- pounds per barrel (lb/bbl)
- pounds per bushel (lb/bu)
