To find out how many 20-inch tiles you will need to cover 100 sq ft, you first need to calculate the area of one tile. A 20-inch square tile covers 20 x 20 = 400 sq inches. Since 1 sq ft = 144 sq inches, you divide 400 by 144 to get approximately 2.78, meaning it will take about 2.78 tiles to cover 1 sq ft. Therefore, to cover 100 sq ft, you will need about 278 tiles.
