MathsThe Soma Cube is made from seven pieces. Each piece contains three or four units. In total the pieces have 27 units, which form a 3×3 cube. 

HistoryThe Soma cube was invented by Piet Hein in 1933 while listening to a lecture on quantum mechanics by famous physicist Werner Heisenberg. Hein was clearly distracted. It became a popular puzzle, and small wooden or plastic versions are still available to buy. Mathematician John Conway thoroughly analysed the puzzle in 1958.

ApplicationsSome puzzles don’t have a direct reallife application, but are good for practising mathematical thinking. When you investigate a puzzle like this, you are learning how to prove things, which are skills you can use to prove more important problems later on. The Soma Cube is a good example of a puzzle that helps you practice your mathematical thinking. 

Maths at HomeYou can make your own Soma Cube at home. You will need to make unit cubes, and attach them to make seven pieces like this: You can even make the unit cubes with paper and origami. Here is a set of instructions and video.
