= 4. The lengths a, b, c of the edges of a rectangular box are changing with time. At the instant in question, we know that a = 1 m, b = 2 m, c = 3 m, da/dt = db/dt = = 1 m/hr, and de/dt = -3 m/hr. At what rates are the box's volume V abc, surface area -S=2(ab+ac+bc), and internal diagonal D = √a² +62 + c² changing at that instant? One more time, start each of these three problems by sketching the corresponding tree diagram and don't forget units with your answers.
