The Volume of a Polygon Based Pyramid Frustum calculator computes the volume of the frustum of right Frustum of Pyramidpyramid with two regular polygon bases (top and bottom) with the same number of sides (n) separated by a height (h).
INSTRUCTIONS: Choose units and enter the following:
Pyramid Volume (V): The calculator returns the volume (V) in cubic meters (m3). However, this can be automatically converted to other volume units (e.g. cubic feet, gallons or liters) via the pull-down menu.
The top and base polygons are defined by the number of sides (n) and the equal side lengths of b and B of the two polygons respectively (see diagram).
The formula for the
V = n⋅h/12⋅(b2+b⋅B+B2)⋅cot(π/n)
