An ice cube is freezing in such a way that the side lengths, in inches, iss of t equals one half times t plus 2, wheretis in hours. The surface area of the ice cube is the functionA(s) = 6s². Part A:Compose an equation that gives the volume at t hours after freezing begins. (2 points) Part B:Find the surface area as a function of time, using composition, and determine its range. (4 points) Part C:After how many hours will the surface area equal 216 square inches? Show all necessary calculations, and check for extraneous solutions. (4 points)
