How many 12x12 inch blocks do you need to lay for a 8 square foot area?

If you have an eight square foot area, and the tiles are 112x12-inches, you will need eight. If what you meant to say was an eight foot square area, that would be 64 square feet, and you would need 64 tile. Sorry! In the first line above should read, "...and the tiles are 12x12-inches..."
