Answer 1

In geometry, a polyhedron (plural polyhedra or polyhedrons) is a solid in three dimensions with flat polygonal faces, straight edges and sharp corners or vertices.

Examples: pyramids

Non Examples : A cone is a solid figure, but is not considered a polyhedron.

Answer 2

Polyhedrons. ... Examples of polyhedrons include a cube, prism, or pyramid. Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons. A prism is a polyhedron with two congruent bases, in parallel planes, and the lateral sides are rectangles.
