A metallic sheet is of rectangular shape with dimensions 48 m x 36 m. From each of its corner, 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 m3) is Choose the correct answer.
A) 6420
B) 8960
C) 5120
D) 4830
E) None
Sol.   Clearly, l = (48 - 16)=

<output>32</output>
32 m,   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) m3 = 5120 m3   Answer 5120
