Minimum surface area box: All boxes with a square base and a volume of 50ft^3 have a surface area given by S(x)=2x^2+200/x, where x is the length of the sides of the base. Find the absoulte minimum of the surface area function. What are the dimensions of the box with minimum surface area?

Best ResponseYou've already chosen the best response.0take the derivative of the surface area function. dS/dx = 4x  200/(x^2) Set it equal to 0 because that is where extrema occur 0 = 4x 200/(x^2) 200 = 4x^3 50 = x^3 x = 3.68
