Appendix 3
Model of a Tetrahedron
and the Related Cube
This appendix contains templates for paper models of a tetrahedron and a cube. The final
shapes are shown in Figure A3.1a. The cube dimensions are set so that the tetrahedron will
just fit inside, as shown in Figure A3.1b. Additional copies of the model templates can be
obtained from the Web site associated with this topic.

Figure A3.1
The completed tetrahedral and cube models: (a) shown separately; (b) with
the tetrahedron inserted into the cube showing the relationship between the two shapes.
To construct the tetrahedron model:
1. Cut around the outline of the pattern, including the flaps.
2. With the printed side of the template downward, fold along all the solid lines; after
folding each of the flaps, push it flat again.
