# Volume of a bipyramid (base regular n-sided polygon)

## Description

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.

## Variables

V | The volume of the bipyramid (m^{3}) |

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) |

π | pi |
