Valume of a box From a rectangular piece of metal having dimensions 24 inches by 36 inches, an open box is to be made by cutting out an identical square of area $x^{2}$ from each corner and turning up the sides. (a) Determine an equation for the volume $V$ of the box in terms of $x .$ (b) Use a table utility to approximate the value of $x$ within $\pm 0.1$ inch that will produce the maximum volume.
