Question: 1 / 400

How many gallons of paint are needed to cover the walls of a room measuring 7'6" by 9'0" with a height of 8'0"?

1 gallon

2 gallons

¾ gallon

To determine how many gallons of paint are needed to cover the walls of the room, first, you need to calculate the total wall surface area that will be painted.

The dimensions of the room are 7 feet 6 inches by 9 feet with a height of 8 feet. To calculate the perimeter of the room, add the lengths of all four walls:

1. First, convert all measurements to feet. The width of the room is 7.5 feet (7 feet + 6 inches which is 0.5 feet) and the length is 9 feet.

2. To find the perimeter:

- Total perimeter = 2 * (width + length)

- Total perimeter = 2 * (7.5 + 9) = 2 * 16.5 = 33 feet

3. Now, calculate the wall area using the height:

- Wall Area = Perimeter * Height

- Wall Area = 33 feet * 8 feet = 264 square feet

Next, you'll need to determine how much area a gallon of paint covers. A standard gallon of paint typically covers about 250 to 400 square feet. For this calculation, let's assume an average coverage of
