sides with length x, then the volume of the box is given by the polynomial

A box is constructed from a square piece of metal that

is 20 inches on a side.

(a) If the square corners of length x are cut out, write

a polynomial that gives the volume of the box.

(b) Evaluate the polynomial when x=4 inches.

(c) Factor out the greatest common factor for this

polynomial expression
