The …A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space. There are no gaps between the edges or vertices in a polyhedron. Examples of polyhedrons include a cube, prism, or pyramid. Non-polyhedrons are cones, spheres, and cylinders because they have sides that are not polygons. Advertisement.

One of the most basic and familiar polyhedrons is the cube. A cube is a regular polyhedron, having six square faces, 12 edges, and eight vertices. Regular Polyhedrons (Platonic Solids) The five regular solids are a special class of polyhedrons, all of whose faces are identical, with each face being a regular polygon. The platonic solids are: …For example, six regular squares can be connected together to form a cube. Such a structure is known as a polyhedron. The polyhedron is regular if, informally speaking, it has as much symmetry as possible. To appreciate better what regular means, position the polyhedron in front of you so that you are directly facing a vertex, and take a …
