It depends on how large the squares are. If they are 12" x 12" it would take 108 of them.
How many squares come in one box. If the squares are 40" x 40", you need 12 of them. You will have scraps left over.
To efficiently install carpet squares in your room, start by measuring the area and purchasing enough squares to cover it. Clean the floor and remove any existing carpet or flooring. Begin in one corner and work your way across the room, laying the squares in a staggered pattern. Use adhesive or double-sided tape to secure the squares in place. Trim any excess material along the edges for a clean finish.
There are 9 square feet in a square yard, so you have 6300 square feet of carpet. Each carpet square is 9 square feet (3 x 3 = 9)... So you would need 700 36" tile squares.

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.
If you buy 18 boxes you will have enough, plus a few extra. 18 boxes will cover just over 434 square feet.
You will need at least 32 square yards of carpet to cover that area.
You will need a minimum of 38.6 square yards of carpet to cover that area.
