A spherical polyhedron is a dodecahedron with 12 faces
A sphere is not a polyhedron because it has no edges, no vertices and no flat faces The word 'polyhedron' means many faces.
6 edges 4 faces and 4 verticies
A polyhedron is a simply connected 3-dimensional simply connected shape which is bounded by polygonal faces. A dodecahedron is a special case of a polyhedron: it is a polyhedron with 12 faces.
A polyhedron can have any number of faces 4 or higher.
no a cuboid is not a polyhedron if it was it would have 9 faces
It is a polyhedron with two congruent faces: nothing more, nothing less. That can change if several additional conditions are required of the polyhedron.
An eight-face polyhedron is called an octahedron.
pentagon
A polyhedron is a solid shape with four or more polygonal faces. A hexahedron is a solid shape with six polygonal faces and so is a particular type of polyhedron.
A nonahedron.
A pentahedron.
