Video Summary

To completely hide the visible faces of the second structure, John needs to add 13 cubes. He covers the topmost cube with one cube and then uses four cubes to cover its side faces. For the sides of the bottom four cubes, which have their top faces already covered, he needs eight additional cubes. Each of these covers an outward-facing side, resulting in a total of 13 cubes added to fully hide the visible surfaces of the second structure.
