A large bin for holding heavy material must be in the shape of a box with an open top and a square base. The base will cost 6 dollars a square foot and the sides will cost 8 dollars a foot. If the volume must be 160 cubic feet. Find the dimensions that will minimize the cost of the box's construction. Find base and each side

You should use the notations such that: x for the lengths of square base and y for the height of box, hence, evaluating the volume of the box yields:

`V = x^2*y => 160 = x^2*y => y = 160/x^2`

You need to evaluate the total surface area of box such that:

`A(x) = x^2 + 4x*y`

You should substitute `160/x^2`  for y in equation of `A(x)`  such that:

`A(x) = x^2 +...
