You are painting a room that is 18 ft long, 14 ft wide and 8 ft high. How much paint will you need to paint the room?
*HINT painting the room, you only paint the walls so that would be calculating the lateral :)
To calculate the amount of paint needed to paint the walls of the room, we need to calculate the total surface area of the walls.
First, calculate the perimeter of the room:
Perimeter = 2(length + width)
Perimeter = 2(18 ft + 14 ft)
Perimeter = 64 ft
Then, calculate the total surface area of the walls:
Total Surface Area = Perimeter x height
Total Surface Area = 64 ft x 8 ft
Total Surface Area = 512 sq ft
Since paint typically covers about 350-400 square feet per gallon, you will need approximately 2 gallons of paint to paint the walls of the room.
