Pieces of the second part

Comment 2 of 2 |

Here's a solution. It turned out not to be very hard to find.

The pieces are:

Three 5x4x1

One 4x4x1

One 4x3x1

One 3x3x1

Three 4x2x1

It was easy enough to fit them in the 5x5x5 that I don't feel the need to show them. The four 1x1x1 bits left over can make an L shape in the top layer.
