A metallic sheet is of rectangular shape with dimensions 40m x 30 m. From each of its corners, a square is cut off so as to make an open box. If the length of the square is 8 m, the volume of the box (in m cube) is:  Choose the correct option.
A) 3220 m cube B) 4140 m cube C) 2688 m cube D) 4000 m cube E) None of these
