Cube and net questions are some of the most feared on NVR papers — but they're actually some of the most learnable.
Opposite-face rule
On a cube net, faces directly across from each other (with one square between them) become opposite when folded. Adjacent faces become adjacent.
Cross nets vs T nets
The classic cross-shaped net (a plus with one extra square) is the most common cube net. T-shapes, zigzags, and crosses all work too. Six squares connected edge-to-edge, with no overlaps, can almost always fold into a cube. Practice now on net questions for visual training.
Spotting the impostor
If a "net" has more than 6 squares, it's wrong. If two squares are floating without an edge connection, it's wrong. If folding mentally makes any two faces overlap, it's wrong.
