(3.10 inch) squared = 9.61 square inches = 62 square centimeters (3.10 square inches) = 20 square centimeters. (both very slightly rounded)
We assume you are referring to 20 thousands of an inch. 1 inch = 25.4mm so 20/1000 inch = 0.508 mm

Depends on the shape of the 400 square foot area, and how you are using the boxes to cover it. The area of one face of a 20 inch cube is 400 square inches. There are 144 square inches in a square foot. So if the area to be covered is rectangular, its the sides are multiples of 20 inches, you could place 144 of the boxes on that rectangle to cover it. If you are talking about cutting the boxes open and using all 6 faces, that's another story. 1/6 of 144 is 24, so 24 boxes opened up have a total area of 400 square feet, but unless you are allowed to cut the boxes further into 20 inch squares, it might be difficult to get them to fit together to cover any reasonably shaped 400 square foot area.
20 inches = 1.666 feet 1.66x 1.666 = 2.777 sq feet 78/2.777 = 28 tiles

The diagonal of a 20 inch square is the square root of 800 inches, approximately 28.284 inches, which is the sum of the squares of two sides.
There are 100*pi square inches in a 20 inch diameter circle
A square 20-inch tile is 2.78 square feet.
A 20-inch diameter circle contains: 314.16 square inches.
If a surface is 144 square feet = 20,736 sq inches, you need at least (172,8 rounded to) 173 tiles (6 by 20 inches) to cover it. Each tile is 6 inch*20inch= 120 sq inch. 20,736 sq inch / 120 sq inch = 172,8. Depending on the shape of the surface you may need more if you have to cut some tiles to make them fit.
