The gallons of paint needed are 7.074 gallons or 7.1 gallons if rounded.
The first step to solve this mathematical problem is to make sure all the values use the same units. This does not occur in the case of the total area given in square feet and the area one gallon covers that is given in square yards.
It is known 3 feet is equal to 1 yard or 3 feet= 1 yard. This implies 9 square feet = 1 square yard. Using this proportion let's make the conversion:
x = 15 square yards
Therefore, one gallon of paint covers 135 square feet.
Total of the area to be painted / area covered by one gallon
955 square feet / 135 square feet = 7.074 gallons or 7.1 gallons if rounded.
