A designer is creating various open-top boxes by cutting four equally-sized squares from the corners of a standard sheet of 8.5 inches by 11-inch paper, and then folding up and securing the resulting 'flaps' to be the sides of the box. Let x represent the varying side length of the square cutouts in inches. Let l,w, and h represent the varying length, width, and height of the box (in inches), respectively. Note that the width and length dimensions are such that w<l. Let V represent the varying volume of the box in cubic inches.
