My original question:
How many gallons of paint are necessary to paint the walls of a 15' by 12' room with an 8' ceiling if one gallon of paint covers 80 square feet?
Your response is quite clear to me. Please write it in simple form. Thanks.
2 walls @ 15 * 8 = 240 sq. feet
2 walls @ 12 * 8 = 192 sq. ft.
240 + 192 = 432 sq. ft.
432 / 80 = ?
192/432 in simplest form
To determine the number of gallons of paint needed to paint the walls of a room, you need to calculate the total surface area of the walls and divide it by the coverage provided by one gallon of paint.
First, calculate the area of each wall by multiplying the height of the wall (which is the same as the ceiling height) by the length of the wall.
For the 15' by 12' room with an 8' ceiling:
- The area of the first wall is 8' x 15' = 120 square feet.
- The area of the second wall is 8' x 12' = 96 square feet.
- The area of the third wall is also 8' x 15' = 120 square feet.
- The area of the fourth wall is also 8' x 12' = 96 square feet.
Now, add up the areas of all four walls to find the total surface area of the walls:
120 + 96 + 120 + 96 = 432 square feet.
Next, divide the total surface area by the coverage provided by one gallon of paint (80 square feet) to find the number of gallons needed:
432 square feet ÷ 80 square feet/gallon = 5.4 gallons (rounded to the nearest decimal).
So, you will need approximately 5.4 gallons of paint to paint the walls of the given room.
