you will need 7 boxes. a room 16' x 13' = 208 square feet. 208sq. ft./ 32.4 = 6.42 boxes. then adding 10% for breakage and cutting you should purchase a minimum of 7 full boxes.
how many boxes of wood flooring would i need if there are 19.72 sq feet in a box to cover 640 sq feet of an area?
A 2,000 square foot blanket will cover an area of approximately 2,000 square feet.
Each tile covers 81 square inches. You have 1,296 square inches to cover. It will take 16 tiles to cover that area.
You will need at least 32 square yards of carpet to cover that area.
The 'square feet' of area that it covers is 1,620/(depth of the mulch, in inches)

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.
