A net is a pattern of two-dimensions that can be folded to make a three-
dimensional figure. You can use 1 cm graph paper to help you make nets.

1. Use
a
net
to
construct
a
rectangular prism.
a. Draw the net at right on a piece
of graph paper. Each rectangle is
10 squares by 4 squares. The two
squares are 4 small squares on
each side.
b. Cut out the net. Fold the net along the edges
of each rectangle to make a rectangular prism.
Tape the edges to hold them in place.
2. Use a net to construct a cylinder.
a. Draw the net at right on a piece of graph
paper. The rectangle is 25 squares by 8
squares. Use a compass to make the circles.
Each circle has a radius of 4 squares.
b. Cut out the net. Fold the net as shown to
make a cylinder. Tape the edges to hold them
in place.
