I have a solid regular tetrahedron whose side is of length 1. I want to pass
this tetrahedron through a circular hole in a flat wall of zero thickness.
What is the minimum radius of the hole in order for this to be possible? You are not required to send a proof this month with your answer (though an explanation of how you got the result would be nice). However, the answer is required to be exact. |
