A cylinder has three faces or individual surfaces. It is a tube-shaped object that is solid on both ends, rather than hollow. It has one face on each end of the cylinder and a third face that wraps continuously around its shaft.
Know MoreEach individual surface of a three-dimensional object is considered a face. Faces are separated by edges. A cube has six faces, and a pyramid has four. While the individual surfaces on cubes and pyramids are easy to count because they are flat, faces are not always flat surfaces. They can also be curved, like the third face on a cylinder. Similarly, a cone has two faces and one edge, and a ball has only one face and no edges.

Full Answer >A rectangular pyramid has five faces, which consists of one rectangular face and four triangular faces. Pyramids are named after the shape of their base, which means a rectangular pyramid has a rectangle for a base.
Full Answer >An icosahedron is a regular polyhedron with 20 faces, all of which are equilateral triangles. An icosahedron has 30 edges and 12 vertices. Five equilateral triangles meet at each vertex.
Full Answer >A cone has one face, one edge and no corners. A cone is defined as a hollow or solid object with a circular base that tapers upward to a point.
