Regular polyhedra have identical faces.
Regular pentagons.

It is a Dodecahedron!
A dodecahedron has 12 faces, and each of these faces is a regular pentagon. Therefore, there are a total of 12 pentagons in a dodecahedron.

The shape of the 12 faces of a regular dodecahedron are regular pentagons.
It is a dodecahedron - a shape with 12 faces which are regular pentagons.

There are a few families of polyhedra with identical faces. There are none whose faces have 6 or more sides. There is no special name for polyhedra whose faces are pentagons or pentagrams. A dodecahedron is an example. If coplanar faces are disallowed, the only polyhedron with quadrilateral faces are the cube and rhombohedron. There are infinitely many polyhedra with equilateral triangular faces: the tetrahedron, octahedron and icosahedron are examples.
A dodecahedron has 12 faces, and each of these faces is a regular pentagon. Therefore, there are a total of 12 pentagons in a dodecahedron.
Platonic solids are convex regular (equiangular) polyhedra. There are five Platonic solids: the tetrahedron, or pyramid (four equilateral triangles for faces; traditionally associated with the element Fire), the octahedron (eight equilateral triangles; traditionally associated with Air), the icosahedron (twenty equilateral triangles; traditionally associated with Water), the cube (six squares for faces; traditionally associated with Earth), and the dodecahedron (which has twelve regular pentagons for faces and is associated with the legendary Luminiferous Aether that had often been considered an element). These are the only existing regular polyhedra that exhibit convexity; other, non-convex regular polyhedra (meaning that there are angles between some of their faces that are less than 180 degrees as measured from the outside surface) exist and are known as star polyhedra.

regular pentagons.... Kyah!
A polyhedron with 12 congruent faces is a dodecahedron.
