First, calculate the area of one 25x25 tile, which is 625 square inches. Convert that to square feet by dividing by 144 (since there are 144 square inches in a square foot), resulting in approximately 4.34 square feet per tile. To cover 400 square feet, you would need about 92 tiles (400 sq ft divided by 4.34 sq ft per tile). Therefore, you will need 92 tiles to cover the area.
You would need 450 tiles
