A metallic sheet is of rectangular shape with dimensions 30 m x 25 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 6 m, the volume of the box (in m cube) is: Choose the correct choice from the following choices:
A) 920 m cube
B) 840 m cube
C) 1000 m cube
D) 120 m cube
E) None of these
Explanation:   l = (30-12)m = 20 m, [because  6+6=
