Prism
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.

cube There are a great many solid shapes that have only flat surfaces.

The flat surface of a solid figure is called a face. For example, a rectangular prism has 6 flat surfaces and therefore 6 faces.

A solid figure that has flat faces that are polygons is called a polyhedron. Polyhedra have various forms, such as cubes, tetrahedra, and octahedra, each defined by the shape and number of their polygonal faces. The faces of a polyhedron are connected by edges, and the points where the edges meet are called vertices. Examples include regular polyhedra, where all faces are identical polygons, such as the Platonic solids.
A SPHERE has no vertices and no FLAT surfaces
