Look on the bag most are 3/4 a foot but 1 bag is called maximum and it is 1 foot. It takes 9 square feet to make a yard you are looking at 13 bags. or the maximum is 9
I'm a contractor so I need to know stuff like this sometimes. Hope that helps.

If you mix it with the correct amount of water.. and the yield is as specified on the bag, it will take 45 bags.... BANK ON IT.
On 60lb bags it takes 54.

One 80# bag = 0.60 cu-ft
Since there are 27 cu-ft per 1 cu-yd, you'll need 27 / 0.60 bags, or 45 bags.
Happy mixing.
