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 m3) is:
4830
5120
6420
8960
Answer: Option
Explanation:

Clearly, l = (48 - 16)m = 32 m,

b = (36 -16)m = 20 m,

h = 8 m.

Volume of the box = (32 x 20 x 8) m3 = 5120 m3.

area of remaining box= area of original box- area of the 4 squares
-------

area of remaining box= (48*36)- 4(8*8) =1728-256=1472

but area in the solution is l*b= 32*20 =640

why the difference?
