a Dodecahedron is a 3 diamentional shape having 12 plain faces in a regular solid figure with 12 equal pentagonal sides!
If they are plane faces the shape is likely to be a polyhedron.
oblong
octahedron
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.

The faces of a cylinder are circles.
A polyhedron (solid shape formed by plane faces) with four faces is called a tetrahedron.
oblong
A plane. * * * * * A plane has no edges. It is infinite in extent.
A 3-D shape with 8 faces is an octahedron.
The following are some examples of a shape with two flat face and one curved surface: A sphere intersected by two planes. An ellipsoid intersected by two plane faces. A paraboloid intersected by two plane faces. A cone intersected by two plane faces. A cylinder. A hyperboloid intersected by two plane faces.
octahedron
An octagon
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.
Any plane shape on the side of a polyhedron is called a face.
