The object obtained after cutting the Mobius strip has one side and it is again a Mobius strip having half width of the original Mobius strip We take a paper strip as shown in the given figure and connect A to Z and B to Y . We draw a line in the centre of the strip without lifting the pen till it reaches the point from where we started . Then we cut the strip along the line . We again get a Mobius strip of half width as mentioned above . This is very easy and

one can do it without any difficulty

We make another Mobius strip and , this time , we draw the line one-third of the way in from one edge , so that the line is off-center , making the width of one side of the line twice as wide as the other . This remains Mobius strip and , hence , has one side

Now we cut the strip along the line we have drawn . We get two Mobius strips which are interlinked together . The width of one strip is half of the other and length of smaller strip width strip is double of the length of the larger width strip

In continuation of the above , the next possibility is cut the higher width strip in middle . We get three Mobius strips of the same width interlinked together . The width as well as length of each strip is same

A geometric shape , which is rough or fragmented and capable of being split into...
