Square feet does not equate to volume.
360 feet = 120 yards.
Given that there are 3 feet in a yard, to convert 360 feet into yards you would divide the number of feet given by 3 to get the number of yards: 360 feet / 3 = 120 yards
There are: 360/3 = 120 yards
360 square feet = 40 square yards.
There are 40 square yards in 360 square feet. (just divide square feet by nine to get square yards).
To calculate the volume of drainage stone needed for a trench, first find the volume in cubic feet: 40 ft (length) × 3 ft (width) × 3 ft (depth) = 360 cubic feet. Since there are 27 cubic feet in a cubic yard, divide the total volume by 27: 360 ÷ 27 = approximately 13.33 cubic yards. Therefore, you will need about 13.33 yards of drainage stone for the trench.
1080 feet = 360 yards
120 yards = 360 feet
120 feet is 40 yards, since there are 3 feet in a yard.
360
360 square yards.
40 square yards = 360 square feet.
