Seven Pieces of the Soma Cube Puzzle.
In 1936, Piet Hein was listening to a lecture on quantum mechanics by Werner Heisenberg. It must have been a really boring lecture, because this is when he invented the Soma Cube Puzzle. Like almost everybody I have been known to daydream during class, but I've never come up with anything constructive.
This wooden puzzle is an arrangement of unit cubes to form seven pieces, which must be assembled into a 3x3x3 cube. The pieces can also be used to make a variety of other interesting 3D shapes.

How to make a Soma cube puzzle.
Making this puzzle is straightforward, there is no need for complicated plans or expensive tools. There is a challenge however, and that is making accurate cuts. The best tool for that is the Stanley 20-800 Contractor Grade Clamping Mitre Box such as this one available from Amazon.com.
The first thing to decide is how big you want to make the puzzle. I made this puzzle from a piece of timber 18mm (3/4 inch) square, and there are 27 cubes in the 3x3x3 puzzle. Which means the timber has to be (27 units x 18mm) = 486mm long plus a bit extra for saw cuts. There are 15 sawcuts to be made, so that means an extra lentgth of (15 x 3mm) = 45mm. So, the total length of material is:
27 x 18mm + 15 x 3mm = 486mm + 45mm = 531mm total length.
It's always a good idea to round it off to the nearest standard length, so I used a piece of timber 600mm long.
A picture is always worth a thousand words.
Now that you have made the puzzle, you are going to drive yourself crazy trying to put it together.
