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:
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.

By we consider the ratio of volume to the curved surface area why not curved surface area to volume to find radius? Please, anyone, tell me.

Hi, since the length of the square is mentioned, can't we use it directly to calculate volume for the box (cube) in this case. 8^3 = 512?

In every side we have deduct 8=8=16.

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?
