Polyhedron (plural polyhedra)
Prism
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.
Flat shapes such as polygons are two-dimensional.
One whose boundaries are straight lines.

Well, honey, shapes that have only flat surfaces are called polygons. Think of your squares, triangles, and pentagons - they're all as flat as a pancake. So, if you're looking for some dimensionless divas, polygons are where it's at.

A sphere
a rectangle
A three-dimensional shape with surfaces that are polygons is called a polyhedron. Examples of polyhedra include cubes, tetrahedrons, and octahedrons, each defined by flat polygonal faces. The edges of these shapes are where the faces meet, and the vertices are the points where the edges converge. Polyhedra can vary in complexity and symmetry, encompassing a wide range of geometric forms.
cube There are a great many solid shapes that have only flat surfaces.
Yes and its flat surface faces are in regular shapes.
