    3 gallons of paint

    Step-by-step explanation:

    Various data is missing, but I think it can be solved with the following assumptions:

    The first thing is to assume that 12 gallons was the exact amount needed for the two rooms.

    If so, we can say the following where x is the size of the smallest room:

    Room 1: It is 2 * x and needs 3 coats of paint, so there would be 6 * x left

    Room 2: is x and uses 2 coats of paint therefore 2 * x

    The paint sum would be as follows:

    6 * x + 2 * x = 8 * x

    8 * x = 12

    x = 12/8 = 3/2

    So:

    Room 1: 6 * 3/2 = 9, 9 gallons of paint needed

    Room 2: 2 * 3/2 = 3, 3 gallons of paint needed

    Room two is the unpainted one so 3 gallons of paint was returned.
