Enter a value for all fields

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 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.

`mass = mu_(density) * volume`

The mean density (`mu_(density)`) 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).

- Rolling Offset (run) - Equation to calculate the run (R) in the diagram above.
- Magnitude of a 3D Vector
- surface area of a box,

- Diagonal of a Square - This is a simple calculation to assist in computing the diagonal of a square.
- Diagonal of a Box - This computes the length of the diagonal of a box (
**T**) based on sides of length**R, S**and**U**. - Flow Rate - This computes flow rate based on the total volume and the time it took to accumulate.
