Tiling A Plane That Has Three Square Holes

I found this tiling on a box this morning.

 

The holes are probably practical constraints required by the boxed products or transport container.

 

This constraint has to be satisfied along with another one: "Fit as many boxes in a truck as possible" and truck manufacturers go to great extents to ensure that the wheel wells do not spoil a nice regular rectangular flat surface on which nice regular flat rectangle boxes can be packed.

 

So, most probably, someone had to be appointed to solve this problem....I can't imagine the job description in that job advert though :-)
