Kathryn's cube of cheese solution

Read the puzzle and have a go before reading the solution.

We think the answer is five. Cutting along the dotted lines we imagine removing the shaded corner of the cube, then similarly for the other three corners leaving a fifth tetrahedron in the middle.



Follow on question (for which I will not provide an answer): What about the other platonic solids?

I can solve the follow-on problem for one of the Platonic solids, the tetrahedron. I'll leave the others to the rest of you.

I have a solution for the other Platonic solids, but I've no idea if I've found the smallest number. I can cut an octahedron into four, a dodecahedron into 36, and an icosahedron into 20. Can anyone do better?
