A metallic sheet is of rectangular shape with dimensions 100 m x 50 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 10 m, the volume of the box (in m cube) is:	Choose the correct choice from the following answers: A) 42500m cube B) 20000 m cube C) 44140 m cube D) 24000m cube E) None of these
Explanation:   l = (100-20)=
