If the walls in a room are 955 square feet in area, and a gallon of paint covers 15 square yards, how many gallons of paint are needed for the room? (3 ft = 1 yd).

Respuesta :

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.

How to convert square yards to square feet?

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:

  • 9 square feet = 1 square yard

               x              = 15 square yards

  • 15 x 9 / 1
  • 135

Therefore, one gallon of paint covers 135 square feet.

How many gallons are required?

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.
