46 Yards or 184 Orders of 1/4 Cubic Yards
So first you need to find the area of the plot; 552. Then you need to find out how much soil you will need. There are 12 inches in a foot so if you have 3 inches you have .25 of a foot. So you multiply 552 by .25 and get 138. 138 is how many cubic feet you need. Therefore, you need to divide this number by 3 in order to convert this to yards (3 feet in a yard). This will bring you to 46. Finally, we need to multiply this number by 4 because they only sell in 1/4 cubic yards.
For number 13 x=70 and y=115 hope this helped
