In this case, one <span>can of paint can covers an area of 400 square units. You are asked how much cans needed </span>to cover an area of 2,200 square units.
Then you just need to divide 2,200 square units with 400 square units. The equation will be : (2,200 square units / 400 square units) x 1 can= 4.5 cans After you round up the result it would be 5 cans.
