TetraCubes A TetraCube is a solid shape
made by joining four identical cubes together, face to face. The Problems:
A.

work well enough if you have them), and a systematic approach, to find as many

Which two tetracubes
will fit together to make a 2 by 2 by 2 cube ? C.
Which four tetracubes
will fit together to make a 2 by 2 by 4 cuboid ? There may be several ways to do
this … D.
Can you see how to
put 6 of these together, with a ‘tricube’ to make up the volume to 27
units, to make the 3 by 3 by 3 ‘Soma’ Cube ? You can use any of the
tetracubes you have found, and either of the tricube possibilities… The Big One Open the File as a Word Document
