WebTherefore, a polyhedron comprises three kinds of geometric objects - vertices, edges and faces. Definition 6. A polyhedron is said to be regular if all its faces are equal regular polygons and the same number of faces meet at every vertex. A polyhedron formed by the {p} polygons with q meeting at every vertex is denoted {p, q}. WebPolyhedrons. A polyhedron is a 3-dimensional figure that is formed by polygons that enclose a region in space. Each polygon in a polyhedron is called a face. The line segment where two faces intersect is called an edge and the point of intersection of two edges is a vertex. There are no gaps between the edges or vertices in a polyhedron.

WebFirst we must take into account the following in order to calculate the area, volume and radius of the regular polyhedrons: A = A = area. V = V = volume. a = a = edge. R = R = radius of the circumscribed sphere. r = r = radius of the inscribed sphere. \rho = ρ = radius of the sphere tangent to the edges.
