Make a model of a cube for your math class or create a giant pair of dice with just a sheet of poster board, scissors, a ruler and some tape. Once you’ve mastered the 6 1/2-inch cube, you can easily make cubes in all sizes.
Things You'll Need
- 28-by-22-inch poster board
- Craft knife (optional)
- Clear packing tape
Measure and mark a 6 1/2-by-1-inch rectangle near the top center of the poster board.
Mark a 6 1/2-inch square below the rectangle with the shapes sharing a side.
Make three more 6 1/2-inch squares below the first, each adjoining the adjacent square.
Measure and mark a 6 1/2-inch square to the left of the second square from the top, again adjoining that square.
Repeat on the right side.
Make a 6 1/2-by-1-inch rectangle on the outside edges of each of the last two squares.
Cut out the cross-shaped template.
Score the remaining lines lightly with your scissors or with a craft knife.
Fold on the scored lines to form the cube.
Tuck the 1-inch tabs into the folded cube.
Tape the edges together with the clear packing tape.
