A sphere
There can be no such shape. If there were a shape with n flat surfaces, then if you sliced off one vertex, you would have a shape with n+1 flat surfaces. So it is always possible to add one more flat surface.
A shape with two flat surfaces and no edges is a cylinder. The two flat surfaces are the circular bases, while the curved surface connecting them has no edges. A cylinder is a three-dimensional shape that extends uniformly between its two bases.
