Problem solving
1 The diagram below needs another square to Key Points
complete the net of a cube. How many different
nets can be drawn? (The colored face must be Try adding a square
on the outside of the cube.) on the outer sides of
the diagram one by
one, and find where
the squares can be
added to complete
the net.
2 Here are three nets that make the same cube Connect the edges
that the figure in the box makes. Draw the or vertices that will
correct pictures in the empty squares. meet when folded.
