1 liter of paint covers 10 square feet of wall. How many liters of paint is needed to cover a wall that's 15ft by 8ft?

15 * 8 = 120 square feet

120 / 10 = _______ liters

10

To find out how many liters of paint are needed to cover a wall that is 15ft by 8ft, you need to calculate the area of the wall and then divide it by the coverage per liter.

First, calculate the area of the wall by multiplying its length by its width:

Area of the wall = Length x Width
Area of the wall = 15ft x 8ft
Area of the wall = 120 square feet

Next, you need to determine how many liters of paint are needed to cover 1 square foot of the wall. It's given that 1 liter of paint covers 10 square feet of wall.

To find out how much paint is needed for 1 square foot, divide 1 by 10:

Amount of paint needed per square foot = 1 liter / 10 square feet
Amount of paint needed per square foot = 0.1 liters

Finally, to find out the total amount of paint needed for the entire wall, divide the total area of the wall by the amount of paint needed per square foot:

Total amount of paint needed = Area of the wall / Amount of paint needed per square foot
Total amount of paint needed = 120 square feet / 0.1 liters
Total amount of paint needed = 1200 liters

Therefore, you would need 1200 liters of paint to cover a wall that is 15ft by 8ft.
