Worked net
On a four-square row A–C–E–F:
- A is two steps from E, so A opposite E.
- C is two steps from F, so C opposite F.
- The two remaining squares are the last opposite pair.
- If two labeled squares share an edge on the net, they cannot be opposite.
Skill
Six squares, eleven unfoldings. When the net becomes a cube, three pairs of faces sit opposite. Adjacent squares on the paper never become opposite.
Look for a straight run of four squares. That belt wraps around the cube. Faces two steps apart on the belt become opposite. The two leftover flaps are the remaining opposite pair.
Foldmetry highlights that belt as a hint, then folds the net into a labeled cube after you answer so the opposite pair is visible in 3D.
