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:
$$area = 6x^2$$
