One interpretation ...

Because of the 'imprint' in the dirt where the 3 piles of bricks lay ?

It is quite reasonable to assume an empty shape like this.

Had the bricks been lying in an array of 4x5 bricks over the dirt, and
stacked 3 high, then there would likewise be a 4x5 'imprint' where they had
been lying.  So the shape is 0 4 5, as in '0 high'.

It's just another quite reasonable way of looking at it.../Rob
