A metallic sheet is of rectangular shape with dimensions 48 m x 36 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 choice.
A) 4120 m cube  B) 4140 m cube  C) 5140 m cube  D) 5120 m cube  E) None of these
Explanation:   l = (48 - 16)= 
<gadget id="calculator">(48 - 16)</gadget>
<output>32</output>
32 m, [because  8+8= 
<gadget id="calculator"> 8+8</gadget>
<output>16</output>
16]   b= (36 -16)= 
<gadget id="calculator">(36 -16)</gadget>
<output>20</output>
20 m,   h= 8 m.   Volume of the box = (32 x 20 x 8) m cube   = 5120 m cube.   Option 5120 m cube
