A polyhedron is said to be regular if its faces are made up of regular polygons and the same number of faces meet at each vertex. Two important members of polyhedron family around are prisms and pyramids. See more A solid whose two faces are parallel plane polygons and the side faces are rectangles is called a prism. A solid whose base and top are … See more A pyramid is a polyhedron whose base is a polygon (of any number of sides) and whose other faces are triangles with a common vertex. 1. A … See more F + V = E + 2 Where F = number of faces V = number of vertices E = number of edges. e.g. Try it on the cube: A cube has 6 Faces, 8 Vertices, and 12 Edges, so: 6 + 8 - 12 = 2 See more The table below shows the number of faces, edges and vertices of each of the platonic solids. Here, v stands for vertices, f for faces and e for … See more WebSolution. The correct option is A. Polyhedron is a 3 dimensional shape having polygons as its faces joined by its edges. Here, the faces of cylinders are not polygons and the edges are not joined by line segments. Thus, cylinder is not a polyhedron. Suggest Corrections.
