Video Summary

The problem involves a 2x2x2 cube with squares on its surface, each featuring a circle, a square, or an X. Adjacent squares must have different shapes, meaning at every vertex, the three touching squares must all display different shapes. Given the constraints, with every vertex needing representation by all three shapes, the solution must present precisely eight instances of each shape considering the cube's layout. The only feasible configuration that adheres to these requirements is "none of the above," as specifically outlined in choice E.
