How do i do part 2
19956.A rectangular box without a lid is to be made from 12 m2 of sheet metal.
i) If the length, width and height of the box are given by , y and z metres respectively, show that the constraint function for this problem is given by:
g(x,y,z)=2xz+2yz +xy-12 =0.
ii) Use the method of Lagrange multipliers and the constraint function given in part (i to determine the maximum possible volume of the box.
