On the boxes it tells you how many sqft a box will cover. Divide that number by 700 and that will give you the number of boxes. You should add at least 10 percent more because of waste. So, you should purchase 770 sqft Labor for that goes for 2 to 3.00 per sqft
You need around 30 boxes but every company have different sizes.. you would have to check .. size
