Hmmm the puzzle last day or so was refined [1] ... However this time around it's clear that the puzzle is in the realm of non euclidean maths, since the bottom left side of the explanatory sketch, placers a right angle and two red angles of 54.74 making a triangle on the face of the cuboid -- 3 internal angles of 90 + 54.74 +54.74 is greater than 180 degrees. Euclidean geometry on the other hand, the internal angles of a triangle sum to equal 180.
