A rectangle is 2.5 times as long as it is wide. Squares of side 4 inches are cut out from each corner. Then the sides are folded up to make an open box. Express the volume of the box as a function of the width (w). O V(w) = 4(w - 4)(2.5w - 8) = 10w² - 72w + 128 V(w) = 4(w - 8)(2.5w - 8) = 10w² - 112w + 256 V(w) = 4(w - 8)(2.5w - 8) = 2.5w2 - 112w + 256 O Y(W) = 4(w - 8(2.5w - 10) = 10w? - 120w + 320
