Heptagonal prism
Introduction 3D model of a (uniform) heptagonal prism.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  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::240px
