    Here's the question:
    Cones P and Q are similar.
    The volume of cone P is 125 times the volume of cone Q
    If the surface area of P is 40cm^3,
    calculate the surface area of Q

    Volume scale factor = linear scale factor^3

    Area scale factor = linear scale factor^2

    So volume scale factor = area scale factor^1.5
