First, Marcus needs to figure out the total square footage of the wall, including the window. Let's say the wall is 20 feet by 10 feet, so the total square footage of the wall is:
20 feet x 10 feet = 200 square feet
Now, let's say the window is 4 feet by 4 feet, so the total square footage of the window is:
4 feet x 4 feet = 16 square feet
To find the square footage of the wall without the window, we can subtract the square footage of the window from the total square footage of the wall:
200 square feet - 16 square feet = 184 square feet
Since Marcus needs to paint two coats on the wall, he will need to double the amount of paint he uses. To find out how many gallons of paint he will need for one coat, he can divide the square footage of the wall by the coverage per gallon:
184 square feet รท 350 square feet per gallon = 0.526 gallons
Since he needs to paint two coats, he will need to double this amount:
0.526 gallons x 2 = 1.052 gallons
So Marcus can expect to use about 1.052 gallons of paint to paint two coats on a large wall with a window centered in the middle of the wall.
Marcus needs to paint a large wall with a window centered in the middle of the wall.
Marcus can expect 1 gallon of paint to cover 350 square feet of wall. If he needs to paint tow coats on this wall, how many gallons of paint can he expect to use?
