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.

How the height of the box is 8?

Here whether the remaining area after deducting the 4 squares is used for making box if it is so then how 8 will come at the place of height.

How is it clear from question that which area have to be used for box?

Take a sheet 48*36 cut each corner 8 unit you will get a shape like # this fold it you will get a open box which dimension 32*20*8 unit. Try to imagine or drawing.

16 has been deducted because in one length of 48cm there ill be two corners.

So its really simply to just deduct length of square two times i.e. 2 * 8 = 16 for two square corner at one line.
