    Let the length, breadth and height of the room be l, b and h respectively.

    First sentence tells you that:

    l = 1.5b

    Second sentence tells you that h = 3.3 m and the volume is 495/4 m^3

    The volume of the room is given by the product of all the three sides, or:



    Substitute in the values you have, and you get:



    You now have two equations with two unknowns. Find l and b. What do you get? :)
