The length l, width w and height h of a box change with time. At a certain instant the dimensions are l = 3 and w = h = 4, and l and w are increasing at a rate of 10 m/s while decreasing at a rate of 1 m/s. At that instant find the rates at which the surface area is changing.
What will be an ideal response?
