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 the substance of the cube (e.g. 10,490 kg/m3 for pure silver)
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.
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).
