Volume of a bipyramid (base regular n-sided polygon)
An n-gonal bipyramid or dipyramid is a polyhedron formed by joining an n-gonal
pyramid and its mirror image base-to-base.
The volume of a bipyramid whose base is a regular n-sided polygon can be calculated by the length of the side of the base and the the height from the base to the apex.
|V||The volume of the bipyramid (m3)|
|n||Number of the sides of the base (dimensionless)|
|h||The height from the base to the apex. (m)|
|s||The length of the side of the base (m)|
