Expert Answer:

Let x cm be the length of each side of the square which should be cut off from corners of the square tin sheet.

          Let V be the volume of the open box

         

         

          So Volume is maximum when x=3

          So volume is maximum when the side of the square to be cut off is 3 cm.
