Net quiz

Does it fold into a cube?

There are 35 shapes made of 6 joined squares, but only 11 of them are nets of a cube. Look at each shape and answer “yes” or “no”. After you answer, it folds up so you can check.

Hints for spotting them

  • At most 4 squares can be in a row. If 5 are in a row, it's not a cube net.
  • If there's a 2×2 block, it's not a cube net.
  • In 3 faces in a straight line, the two ends are opposite. Check that you get 3 pairs of opposite faces.
