On a single face of the cube, mark each point along the section with the appropriate letter. Using compass and a ruler, construct a series of triangles and/or rectangles all having one vertex or corner in "Z" (the center of the cube). Connect the various shapes together to complete the INTERNAL surface of the cube. Once you solve one section, all you have to do is repeat the pattern on the other three faces. This is your "master" drawing, which will be used to construct the final cube. Do not cut the master drawing, use a push-pin to transfer the shapes onto separate cardboard. Full scale.
Using paperboard or other card stock, construct a rough cube to test the correct section. Use scotch tape or glue to connect the parts but make sure the parts themselves are precisely cut. This rough model is meant to confirm that the section will work. Construct the section leaving the bottom open until the end.
See also a more recent video (2014) that uses a clever "circle grid" devised by a former student (Slate Werner) to draw the internal parts more efficiently.
