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.

The height will be 8m because the square of 8m is given and it is square so length will be nothing but height.
Imagine a square of 8m it has only two parameters.
Length and breadth, when that square is placed in rectangle then length will be height.

It's is so easy..we have given length 48 and breadth 36 of a box.
Now a square of 8 m is cut from 4 corners of the above box means 4 small boxes at 4 corners of the box are formed. Now we'll find the volume of the remaining box. Now,
New length of the box = 48-(8+8) = 32m,
New breath of the box = 36-(8+8) = 20m,
New height = 8m.
So volume = l*b*h = 32*20*8 = 5120 cubic meter.

Thanks @Hemant.

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.

How can we take h=8? it is not given.

@All.
To make an open box, the sheet is to be moulded after cutting 4 squares. Then effective length becomes 32m and breadth becomes 20 m and the height of the box is the length of square taken off (i.e =8 m).
Volume of box is 32 * 20 * 8.
