Why do some nets for a cube work and some don't?

A net for a cube must consist of six connected squares that can be folded along the edges to form the three-dimensional shape. If the squares in a net are not properly connected or are arranged in such a way that they cannot fold into a cube without overlapping or leaving gaps, then that net will not work. Additionally, the spatial arrangement must ensure that each square corresponds to one face of the cube, maintaining the correct geometry. Therefore, only certain configurations of squares can successfully form a cube when folded.
