(a) A polyhedron with 4 vertices and 4 faces is tetrahedron.
(b) The only Solid object with no vertex is Sphere.
(c) The possible polyhedrons with 12 edges are a cube, cuboid, Hexagonal Pyramid.
(d) The Only solid object with 1 face is Sphere.
(e) Cube is a Regular Polyhedron (All faces are identical)
Whereas Cuboid is not a Regular Polyhedron (All faces are not identical)
(f) Cube and Cuboid have a same number of faces, edges, vertices.
That is 6 faces, 12 edges, 8 vertices.
(g) A Polyhedron with 5 vertices and 5 faces is square Pyramid.
