A rectangular box is created by cutting out squares of equal sides

of lengths x from a piece of cardboard 10 inches by 15 inches and

folding up the sides as shown in the figure. The volume of the box is

given by V = x (10 - 2x) (15 - 2x). Find the volume of the box when

the side length of the square is 3 inches.
