How would I take the derivative of this equation then with multiple variables?

So after substituting that in for h, the simplified form would be: A= 4V-5x\sqrt{3}+ 9\sqrt{x^2+4} \sqrt{3}

How would I use a formula for volume since the problem works with two shapes. V=(3\sqrt{3})/2 a^2*h h= V/ (3\sqrt{3}/2 a^2*h Then, I can just plug this into the first equation, simplify, and start the calculus. Is that right?
