How many 2x2x2x2 tiles would be needed for a 6 square feet?

To determine how many 2x2x2x2 tiles are needed for a 6 square foot area, we first need to calculate the area covered by one tile. A 2x2 tile covers 4 square feet (2 feet x 2 feet). Therefore, to cover 6 square feet, you would need 6 / 4 = 1.5 tiles. Since you can't have half a tile, you would need 2 tiles to cover the area adequately.
