Problem Statement

A parallelogram of paper with sides 2525 and 1010 is given. The distance between the longer sides is 66. The paper should be cut into exactly two parts in such a way that one can stick both the pieces together and fold it in a suitable manner to form a cube of suitable edge length without any further cuts and overlaps. Show that it is really possible and describe such a fragmentation.
