|These blocks can be packed into a larger cubical box with no spaces unoccupied and nothing sticking out. This looks very easy. It is not! Both this puzzle and the previous can be reasoned; it's not just a matter of trial and error.|
|The majority of
the blocks are those brick shaped ones. There are thirteen of them,
each one unit by two units by four units. There are three blocks
one by one by three units. There is one block one by two by two units,
and one block two by two by two units.
