The tetrahedron has only four faces. A sphere has only one, but that's probably not what you meant since the surface of a sphere is curved.
a sphere has no edgesOf the solids with planar faces and line edges the tetrahedron has the fewest edges and faces. (Four faces and six edges)

The Platonic solids, in order of number of faces, are:Tetrahedron - 4Cube - 6Octahedron - 8Dodecahedron - 12Icosahedron - 20Therefore, the fewest number of faces of a Platonic solid can be found on a tetrahedron.
4The minimum number of face a polyhedron can have is four.
A __________ is a space figure in which all faces are polygons.
'Enneahedron' - a solid figure with nine faces
A heptagon is a space figure with 7 faces
A solid figure with twenty faces is called an Icosahedron.
A figure that has six rectangular faces is a rectangular prism.
A tetrahedron (triangular pyramid).
Such a figure is a triangle-based prism.
