The Weight or Mass of a Cube calculator computes the mass or weight of a cube based on the length of a side (s) and mean density (mD). 
INSTRUCTIONS: Choose units and enter the following:
- (s) Side Length of cube (see diagram)
- (mD) mean Density of cube material (e.g., 7,850 kg/m3 for steel is the default)
Mass or Weight of a Cube (M): The calculator returns the mass in grams (g) and the volume in cubic centimeters (cc). However, this can be automatically converted to other mass or weight units (e.g. ounces) via the pull-down menu.
The Math / Science
The formula for the mass or weight of a cube is:
M = s3 ⋅ mD
where:
- M = mass of the cube
- s = length of any side
- mD = Mean Density of the material
With the computed volume, this formula then executes the simple equation below to compute the approximate mass of the object.

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)
If you want to identify a material by its density, use the Density Within Range tool.
Weight is technically the downward force that a mass exerts based on the force of gravity and the mass of the object. On the surface of the Earth, mass and weight are often interchanged. In some places, objects are sold by the gram (mass), and in other locations, the same objects are sold by the ounce (weight). 
The Weight Calculators use the dimensions of an object and its shape to compute the objects volume. They then apply a density associated with a material to estimate the objects weight.
