    I have had a go and I am even more confused now as I have no K anywhere,

    I have written down:

    Area= 6x2
    Volume= x3

    dA/dX= 12x
    dV/dX= 3x squared

    dA/dT= da/dX x dX/dV x dV/dT

    = 12x x 1/3x squared x 1/2 V to the power 1/3?

    am I completely going the wrong way?
    That's all correct so far (as far as I can see) now just find dA/dT in terms of A only.
