A heptagonal prism is a prism with a heptagon (7-sided polygon) as its base. It has 14 faces (2 heptagons and 12 rectangles), 20 vertices (2 at each corner of the heptagon and 2 at each corner of the rectangles), and 28 edges (7 edges on each heptagon base and 12 edges around the sides connecting the corresponding vertices of the base and top heptagon).

A heptagonal prism has two 7-sided bases.
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. 7 faces, 15 edges, 10 vertices
the heptagonal prism. two bases that are heptagons- (7 sided) and 7 other faces. 7+2=9! [:
There are a number of possible 7-sided polyhedra. Three that come immediately to mind are: a hexagonal pyramid, a pentagonal prism, a "stretched" triangular pyramid (triangular base, rectangular sides, and then triangular faces meeting at an apex).

A heptagon is a 7-sided polygon, so a heptagonal prism is a 3D version of that (9 sides, 21 edges, 14 vertices).
