Re: Biggest triangle in a cube
hi Stefy,
I must have been busy on 30th May.
I offer the solution to part two in the diagram below. The area is easily worked out using half ABsinC and Pythag.
I suspect it is also the answer to part one.

Re: Biggest triangle in a cube
Do you have a proof that is the solution?

Nope. I will try to think of something.
