I cut off one corner of an empty box to form an open 'pocket', so that each of the length a, breadth b, and depth c, of the initial corner was a different whole number of centimetres, and the area of each face of the 'pocket' was also an integer.
What is the area of the open 4th side of the 'pocket', in terms of a,b, and c?
(In reply to
what is wanted? by Charlie)
I noted some instances where the a, b and c were not all distinct. I've now also counted only those instances where the 4th side also has integer area:
