A painter is going to paint a room shaped like a cube, with square walls that are 20 ft. on each side. A gallon of paint can be used to cover 400 square feet. How many gallons of paint should the painter guy if he is going to paint the four walls of the room? Explain to me how u found it?

Answer 1

To find out how many gallons of paint the painter guy needs to paint the four walls of the room, we first need to find the total area of the four walls.

Each wall is a square with sides of 20 ft, so the area of one wall is 20 ft * 20 ft = 400 square ft.

Since there are four walls in total, the combined area is 400 square ft * 4 = 1600 square ft.

Now, we know that a gallon of paint can cover 400 square ft, so to find out how many gallons are needed, we divide the combined area by the area covered by one gallon of paint:

1600 square ft / 400 square ft/gallon = 4 gallons.

Therefore, the painter guy needs 4 gallons of paint to paint the four walls of the room.
