Cylinders polyhedron
WebA cylinder is not a polyhedron because it has a curved surface. Polyhedrons have flat surfaces, called faces, which are made of polygons. For example, prisms and pyramids come under polyhedrons. Why a three-dimensional figure with a curved surface is not a polyhedron? Explanation: The definition of polyhedron implies that each side is a piece ... WebThe cylinder is not a polyhedron, so the faces, the vertices and the edges of the cylinders are considered in a slightly different way than polyhedra like the cube, the prism and others. However, we can give it a structure …
