In geometry, the heptagonal prism is a prism with heptagonal base. This polyhedron has 9 faces (2 bases and 7 sides), 21 edges, and 14 vertices.

Area

The area of a right heptagonal prism with height h and with a side length of L and apothem a_p is given by:

Volume

The volume is found by taking the area of the base, with a side length of L and apothem a_p, and multiplying it by the height h, giving the formula: This formula also works for the oblique prism due to the Cavalieri's principle.
