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.
Common Mean Densities (mD)
- 1,000 kg/m3 - Pure Water
- 1,022 kg/m3 - Sea water
- 1,037 kg/m3 - Milk
- 860 kg/m3 - Olive Oil
- 885 kg/m3 - Diesel Fuel
- 870 - 920 kg/m3 - Crude Oil
- 890 kg/m3 - Fuel Oil
- 789 kg/m3 - Ethanol
- 737 kg/m3 - Gasoline (petrol)
- 1,442 kg/m3 - Cement Slurry
- 2,830 kg/m3 - Aluminum
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.
`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).
Box Calculators
- Rolling Offset (run) - Equation to calculate the run (R) in the diagram above.
- Magnitude of a 3D Vector
- surface area of a box,
- volume of a box,
- diagonal of a box and
- weight of a box if full when you provide the mean density
- weight of a box if full and you can select any of 500+ substances
General Plumbing Calculators
- Rolling Offsets (Run) – The Rolling Offset (Run) function computes the run length a rolling offset based on the offsets and fittings. (see diagram).
- Rolling Offsets (Travel) – The Rolling Offset (Travel) function computes the travel pipe length a rolling offset based on the offsets and fittings. (see diagram).
- Pipe Grading - The amount of drop needed over a run to maintain a specified grade
- 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.
- Pipe Flow Volume - This computes the total volume from a pipe based on the flow rated and the duration of flow.
