  3. Who makes up these questions or what kind of strange paint is this?
    To paint a ceiling of that size should take about 1/2 gallon
    ( I know, I have too much time on my hand)

  5. The room is 15x15 feet, making 225 sq ft.
    Each gallon covers 45 sq ft

    5*45 = 225, so it will take 5 gallons.
    Or, as we solved it, 225/45 = 5
