Find the ratio of the volume of tetrahedron with that of the tetrahedron formed by the centroids of its faces. Given Volume of tetrahedron `=1/3 times` area of base triangle `times` height of vertex.

Prove that the volume of the tetrahedron and that formed by the centroids of the faces are in the ratio of 27:1.

Prove that the volume of the tetrahedron and that formed by the centroids of the faces are in the ratio of 27:1.
