The Pyramid Calculator contains equations related to objects shaped like a geometric pyramid. Basic Pyramid  This includes equations for volume, surface area and mass.

# Description

Pyramids can have bases of triangles, squared and polygons.  The pyramids can be full pyramids or frustums. A frustum is made by parallel planes slicing through an object.  The equations in this calculator include formula for the volume and mass of pyramid shaped objects. Polygon based pyramid Pyramid Frustum Polygon pyramid frustum

## Mean Density

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.
