`M = [1/3 * "A" * "h" ] * "mD" `

Enter a value for all fields

The** Pyramid Weight (Mass)** calculator computes the weight or mass of a pyramid of base area (A), height (h) and mean density (mD).

**INSTRUCTIONS:** Choose the units you wish for area (e.g. cm^{2}) and height (e.g. inches) and enter the following:

- (
**A**) Area of the base of the pyramid - (
**h**) Height of the pyramid - (
**mD**) Mean density of the composition of the pyramid (e.g. 2,400 kg/m^{3}for concrete)

**Pyramid Weight (M):** The calculator returns the weight/mass in kilograms. However the user can automatically convert this to many other mass/weight units (e.g. pound or tons) via the pull-down menu.

The formula for the mass or weight of a pyramid is:

` M = [1/3 * A * h] * mD`

where:

- M = Mass of pyramid
- A = Area of Base
- h = height of pyramid
- mD = Mean Density Pyramid Material

This formula computes the volume of the pyramid shape based on the input parameters. With the computed volume, this formula then executes the simple equation below to compute the approximate mass of the object.

where:

- M = Mass or Weight of Pyramid
- μ = density of material (e.g. limestone is 2691 kg/m
^{3}) in the pyramid - V = Volume of the Pyramid

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).

- Mean Density of Many Substances: The Mean Density Lookup equation provides the mean density of hundreds (650+) substances from metals to gases, woods, food, liquids and much more. The results of the Mean Density look-up are in kg/m
^{3}. Use the answer for the substance you choose in the mass equation to approximate the mass or weight of the pyramid shaped object based on its shape, dimensions and the mean density of its composition.
