IPP 1819 Packing (IPP19 exchange)

Designed by Rik himself,
Produced by Kevin Holmes.

Pack the pentacubes in the box so that the lower layer appears filled, and the upper layer shows '19' in stead of '18'.

The booklet describes how the puzzle was invented and analysed. It also contains the 'solution' for the '18' layout.

The voxel size is 10mm, hence the solution measures 90 x 70 x 20 mm. The box is slightly larger.
