An open box is to be made from a piece of cardboard 11 in by 17 in, by cutting out a square of length x from each corner and turning up the sides. Express the volume V of the box as a function of the length x of the side of the square cur from each corner.

Length of box = 172x
width of box = 112x
height of box = x
volume = x(172x)(112x)
