A pyramid
It has one flat face if its 2 dimensional. It has 6 flat faces if it is 3 dimensional.
A tetrahedron (4 triangular faces) is the only polyhedron that has a unique configuration of faces, edges and vertices. For any polyhedron with n (>4) faces, there is a prism with a pair of n-2 sided polygons as bases as well a pyramid whose base is an n-1 sided polygon. There are many other configurations for polyhedra with more faces. For example, there are ten [topologically] different figures with 6 faces: 3 of these are concave polyhedra.
An object cannot be 3-dimensional and plane at the same time since the term "plane" refers to 2-dimensional objects, such as geometric figures drawn on a sheet of paper. However, certain 3-dimensional objects, for instance a cube, are comprised of 2-dimensional (plane) figures (in this case, 6 of them). On the other hand, a sphere has no plane faces (but theortically approaches an infinite number of them) since no aspect of a sphere can be truly represented on a flat (plane) surface. For practical purposes though, each tiny portion of the sphere could be thought of as a plane figure, and a perfect example of this is a road map.

Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
A cube has 6 faces and 24 corners. A square has 1 face and 4 corners
