Polyhedron These are the triangular pyramid or tetrahedron, cube or hexahedron, octahedron, dodecahedron and icosahedron: Polyhedra of the highest symmetries have all of some kind of element - faces, edges and/or vertices, within a single symmetry orbit.

Polyhedron Polyhedra with congruent regular faces of six or more sides are all non-convex, because the vertex of three regular hexagons defines a plane. The total number of convex polyhedra with equal regular faces is thus ten, comprising the five Platonic solids and the five non-uniform deltahedra.

How many faces, edges and vertices does a hexagonal pyramid have? A pentagonal pyramid has 6 faces, 6 vertices, and 10 edges. Hexagonal pyramid: 7 faces, 7 vertices, 12 edges. And so on. There is a general formula based upon the shape of the base. If the base has X number of sides, the pyramid has X +1 faces, X+1 vertices, and 2X edges.

polyhedron A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles. Although regular polygons are possible for any number of sides, there are only five possible regular polyhedrons, having congruent faces, each a regular polygon and meeting at equal angles.

Shape: Face A face is one of the polygonal surfaces of a polyhedron. This rectangular prism has six faces. We can see three of them (blue, purple, and green); the other three are hidden from view. This polyhedron has eight faces. We can see five of them -- four rectangles (of which the blue, purple, and red ones appear to be square), and a green L-shaped six-sided figure (hexagon).

How many faces does an octagonal prism have? An octagonal prism has 10 faces. The octagonal prism can be seen to have ended shaped like octagons. That's an 8-sided figure. is a 3-dimensional form, and if it has octagons on each end, it is going to have 8 faces. That's a face for each side of the octagon. The 8 faces of the body of the prism are added to the two faces (one on each end) for a total of 10 faces. (The illustration is a pentagonal prism.). An n-gonal prism has n+2 faces.

Hexagonal prism In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has eight faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces.
