A metallic sheet is of rectangular shape with dimensions 20 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 2 m, the volume of the box (in m cube) is:
Select the correct option:
A) 4120 m cube
B) 4140 m cube
C) 5140 m cube
D) 1344 m cube
E) None of these
Explanation:   l = (20- 4)=

4]   b= (25 -4)= 
<gadget id="calculator">(25 -4)</gadget>
<output>21</output>
21 m,   h= 2 m.   Volume of the box = (16 X 21 X 4) m cube   = 1344 m cube.   Option 1344 m cube
