Tetrahedron Circumscribing

The (not necessarily regular) tetrahedron of least volume circumscribed around a convex body  with volume  is not known. If  is a parallelepiped, then the smallest-volume tetrahedron containing it has volume 9/2. It is conjectured that this is the worst possible fit for the general problem, but this remains unproved.
