Required
Which covers more plane
The large square has the highest dimension and by extension, it has the highest area.
This means that, less large squares will be needed to cover more areas compared to other sizes of the squares.
Take for instance, the following analysis;
Large square
Dimension: 3 by 3;
Medium Square
Dimension: 2 by 2
Small square
Dimension: 1 by 1
The square with the largest area covers more of the plane.
Hence, the large square covers more of the plane
