Design by Oskar van Deventer

This puzzle is just one cube, but this cube has to be sawn in different pieces, in three cuts. The eight pieces you get in this way has to be rearranged to form a new cube which is a fraction bigger than its original. This looks like magic, but it is possible.

If you make this puzzle you need a firm cube and a good saw. You can think by yourself how to cut the cube in eight pieces. For a hint you can use the diagram below in which a square of 64 small squares is cut and rearranged into a square of 68 small squares. 

If you look at the design graph you can exactly see how to cut the cube. You can also download a paper model of this puzzle..
