Apr 8, 2015 at 8:03 comment added The Masked Avenger hmm. Two unit tetrahedra seem to cover a cube of side length root(2)/3. Add one for each face and edge of the unit cube, and I get 34 total.
Apr 8, 2015 at 4:43 comment added The Masked Avenger If you take two tetrahedra, put them base to base, twist one 60 degrees, then smash them together, you might get something that covers a cube of side length close to 1/2. In any case, I'm guessing the required number of tetrahedra is close to 20.
