A heptahedron is a closed 3-d shape with 7 polygonal faces. There are 34 topologically different convex heptahedra and, since none of these are regular, the term is ambiguous. Only the right pentagonal prism, a very special version of one of the 34 topological forms has 5 faces which are perprdicular to the other 2.
A pentagonal heptahedron. A heptahedron is a solid figure with seven faces, and a pentagon is a five-sided plane figure.
A heptahedron is a polyhedron with seven faces. The number of vertices in a heptahedron can be determined using Euler's formula, which states that for any polyhedron, the number of vertices (V), edges (E), and faces (F) are related by the equation V - E + F = 2. Since a heptahedron has 7 faces, the equation becomes V - E + 7 = 2. The number of edges in a heptahedron can vary depending on its specific shape, so the number of vertices cannot be determined without additional information about the edges.
This shape has 2 opposite identical faces and some other which are parallelograms is a prism. A cylinder shape has 2 circular faces and one curved face.

hexagon base prism
rectangular prism.It has 6 faces and 12 edges. The 2 bases are congruent to each other, and the remaining 4 faces are congruent to each other, but the bases are not necessarily congruent to the other faces.
