None. Because 'yars' is a linear measure. You need a 'Cubic' measure. You gave two dimensions a length and a width. However, you also need to know the depth, in order to give you the volume of concrete needed in 'cubic feet'. To convert 'cubic feet' to 'cubic yards' divde cubic feet by '27'.
One square yard is nine square feet, so 27 square feet is equivalent to 3 square yards. So 3 yards of concrete will cover 27 square feet.
How many square yards in a 20x18 feet 3 inches thick
To calculate the amount of concrete needed for a 900 square foot area, you first need to determine the thickness of the concrete slab. Once you have the thickness in inches, divide it by 36 to convert to yards. Then divide the total cubic yards by the number of cubic yards in a concrete truck to determine how many truckloads you need.
