Heptagonal prism
In geometry, the heptagonal prism is a prism with heptagonal base. This polyhedron has 9 faces, 21 edges, and 14 vertices.Area
The area of a right heptagonal prism with height and with a side length of and apothem is given by:Volume
The volume is found by taking the area of the base, with a side length of and apothem, and multiplying it by the height, giving the formula:
This formula also works for the oblique prism due to the Cavalieri's principle.Images
The heptagonal prism can also be seen as a tiling on a sphere:
