Pentagonal prism

It is a type of heptahedron with seven faces, fifteen edges, and ten vertices.

If faces are all regular, the pentagonal prism is a semiregular polyhedron, more generally, a uniform polyhedron, and the third in an infinite set of prisms formed by square sides and two regular polygon caps.

It can be seen as a truncated pentagonal hosohedron, represented by Schläfli symbol t{2,5}.

For a uniform pentagonal prism with edges h the formula is Nonuniform pentagonal prisms called pentaprisms are also used in optics to rotate an image through a right angle without changing its chirality.

It exists as cells of four nonprismatic uniform 4-polytopes in four dimensions: This polyhedron-related article is a stub.
