A small sphere is centered at a corner of a large cube. What proportion of the surface of the sphere is inside of the cube?
Answer the same question with the cube replaced with a regular octahedron.

You can easily fit 6 octahedra with room to spare, so the answer must be less than 1/6.

If you think about it, an octahedron is "pointier" than a cube, so the answer is probably less than 1/8.
(incidentally, I agree with Charlie's answer, but my method is simpler.)
