Cardboard (packing material) 3 pieces of sizes a, b, c |
| |
a : 7.5 cm x 30 cm (3 in.x 12in) |
| |

|
Method :
1. Mark the cardboard
strip (a) into three sections, each 10 cm (4 in.) wide. Fold the marked
sections into a triangle and hold it with tape. |
 |
2. To make a bottom piece, place the box onto the large piece of cardboard
strip (c) and trace
around the edge. Cut out the shape. Tape the bottom in place.
3. To make top for the box, place the bottom piece cut out, again
on the remaining cardboard strip (c) and mark with the pencil around.
Cut just outside the lines you drew, making a top shape slightly larger
than the bottom shape. |
 |
4. To make the sides of the lid, place the larger triangle at one end of the
long narrow strip (b). Mark the length of the
triangle. Mark three equal sections on the narrow strip and trim off the small
section remaining at the end. Fold each section into a triangle shape and tape the top to it. |
