Suppose you have some unusual 3-dimensional object so that w and h are the only measurements of the object that are needed to determine it's volume and surface area. Use the following volume and surface area formulas to answer the questions. V- lwit and 5 - 4wh + w? (a) If the volume of the object is 18 cubic feet, express the object's total surface area only in terms of w. S(W) - Select- (b) Find S(w) (c) Find the exact value of w that minimizes the total surface area of the object. W -Select
