13 A closed pizza box is folded from a sheet of cardboard 66 cm by 40 cm. To achieve this, the cardboard is cut as shown in the diagram. 1296-72-7 -66 cm 1296-1448 т 0 = 324-36x 40 cm a Find the dimensions of the closed box in terms of x. (40-2x)(66- 6 Show that the volume of the box is given by V = 3r3 - 126r2 + 1320 cm. 256x + 1320 d Hence find the maximum possible volume of the box, and the dimensions of the box which Find V'(x). CX- give this result. 3 em". (46.2
