- If you need 5 corners immovable to keep other corresponding corners intact, you could technically just use 5 pieces of tape. Just run one piece of tape along the seam, around the edge, connecting 4 squares per corner. 2 squares on 2 faces, then neither of the 3 faces could change on the corner. You might be able to do it with 4, but I woiled have to hold a cube to visualize it, and I don't have one. This is the minimum, but unless you have perfect tape, you would need more.
