A dodecahedron is 3-dimensonal shape with 12 faces. There are 6,384,634 topologically distinct convex dodecahedra, excluding mirror images, having at least 8 vertices (corners).
Some examples:
5 faces, 5 corners.
12 edges 6 faces 8 corners
Zero corners and edges, and a cyllindar has two faces.
A cilinder has: 3 faces, 0 corners and 2 edges.
If it is a polyhedron, then four or more faces and four or more corners.
3 faces and 8 corners
A sphere has no faces an corners. The term "faces" and "corners" are applied to polyhedrons, figures with flat surfaces.
6 faces 8 corners
No corners, two faces
5 faces, 5 corners.
5 corners and 5 faces 5 corners and 5 faces
11 faces and 11 corners (vertices).
12 edges 6 faces 8 corners
Zero corners and edges, and a cyllindar has two faces.
A pyramid has 5 faces, 5 corners and 8 edges corners and faces are always the same
there are no corners and there are 3 faces
Cuboid has : 8 corners (vertices) 12 edges 6 faces
