Cube net

The net of a cube consists of 6 squares, as shown below:

Use the Fold/Unfold button to fold or unfold the net. You can also drag the shape with the mouse to spin it around.

For a cube of length $x$, the surface area of each square of the net is $x^2$ so the total surface area of all 6 squares is:

$$area = 6x^2$$
