You plan to make a box with a square base and lid, with the largest possible volume, and with surface area 140in^2 a) If the square base of the box is x inches wide, determine a formula for the function V (x) representing the volume of the box (in cubic inches). Your function should contain the variable x and cannot contain any other variables. b) Determine a domain for V(x) which makes sense in the context of the scenario. Briefly explain why you chose the domain you provided c) Determine the largest possible volume of such a box. You must use calculus to verify that the volume you find is the largest possible volume
