Problem Statement

Let be given an arbitrary tetrahedron ABCDABCD with volume VV. Consider all lines which pass through the barycenter SS of the tetrahedron and intersect the edges AD,BD,CDAD,BD,CD at points A,B,CA',B',C respectively. It is known that among the obtained tetrahedra there exists one with the minimal volume. Express this minimal volume in terms of VV
