8 Nets
Basic Concepts The Net of a Cube
A net is a diagram that shows what a solid object looks like when it is
unfolded.
Solid figure Net
There are 11 different ways to draw a cube net. If one net matches
another net after being flipped or rotated, the two nets are considered the
same.
Example Which diagrams below are not the nets of a cube?
Class Notes
Since a cube has faces that meet at a single vertex, the diagram
that has four faces meeting at one vertex, , is not a cube net.
Every face of a cube has opposite face, but cannot be a
cube net because it has the face D, with two opposite faces. A
BCDE F
Therefore, the diagrams that are not the nets of a cube are and
.
Try It Again The diagram needs another square in order to
complete the net of a cube. Write the numbers
of all the locations where you can add the
square.
