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..
