An open box is built in the shape of a cuboid, with the length of the base twice as long as the width of the base, to maximise the volume. The total surface area of the box is 5400 square centimetres, let x be the width of the box and h be the height of the box. If height is h=2700-x2/3x Show that v=1800x-2/3x3 (minus two third x3)
