    May I add that the solution to the equation 2x^2 - x - 120 = 0 is that x = 8, not x = -7.5 as it is length so it cannot be negative.
    yes i worked out the 2 number then i chose 8 !

    I got something like 102.4 for the vase, but how can the surface area be less than be volume? I was so confused. Pretty sure I was right, you square root the scale factor then cube it and divide.

    Surface area is cm2 and volume is cm3, right?
    So volume must be bigger because you cube it whereas for surface area you square it.
