Mr.savage used 3 gallons of paint to cover 1350 of square feet of wall .at this rate how much paint wiil be needed to cover 1800 square feet.
1800/1350 * 3
To find out how much paint will be needed to cover 1800 square feet of wall, we can use a proportion.
First, let's set up the proportion using the given information:
3 gallons of paint covers 1350 square feet of wall
Now, we can set up the proportional relationship:
3 gallons / 1350 square feet = x gallons / 1800 square feet
To solve for x, we can cross multiply and then solve for it:
3 * 1800 = 1350 * x
5400 = 1350x
Now, divide both sides of the equation by 1350 to solve for x:
5400 / 1350 = x
x = 4
So, it will take 4 gallons of paint to cover 1800 square feet of wall.
