What are the steps to name the solid that a net folds into?

e.g. a net made of 2 circles and 1 rectangle

1. Name the flat shapes in the net: 2 circles and 1 rectangle.
2. Spot the pair of identical faces — these become the ends: the 2 circles.
3. Name the solid with that cross-section: a cylinder.

True or false? Any 6 squares joined edge to edge form a net of a cube.
