The number of edges of any polyhedron can be calculated using the formula: E = V + F - 2, where "E'" denotes the number of edges, "V" indicates the number of vertices and "F" represents the number of faces. It is derived... More »

A pyramid with a hexagon-shaped base has 12 edges, seven faces and seven vertices (points where edges meet). The qualities of a polyhedron are intrinsically related to one another, as is shown using an equation called Eu... More »

A tetrahedron is a three-dimensional shape that contains four vertices, four faces and six edges. This Platonic solid is classified as a polyhedron, specifically a regular convex polyhedron. This indicates that all the f... More »

A vertex is a corner on a polygon, polytope or polyhedron, and when faces, facets or edges of an object come together, a vertex forms; however, because a sphere features no meeting points, it has no vertices. Even though... More »

A sphere has no faces, edges or vertices. By definition, it is a curved three-dimensional geometric figure whose surface is defined as the set of all the points equidistant from its center point. More » Math Geometry Shapes

A tetrahedron is a three-dimensional object that has four faces, six edges, and four vertices, or points. It can be thought of as a pyramid with a triangular base. Regular tetrahedrons are made of four equilateral triang... More » Math Geometry Shapes

A square pyramid, a pyramid with four triangular sides and one square side, is a figure with five faces, eight edges and five vertices. It is a kind of three-dimensional solid. The pyramids at Giza, Egypt are examples of... More »
