An octahedron: two quadrilateral based pyramids with their bases together.
A triangular prism has two triangular bases and three lateral rectangular faces. It has five faces in all so that it is a pentahedron.A triangular pyramid has a triangular base and three triangular lateral faces. It has 4 faces in all so that it is a tetrahedron.
