Admin is wrong. To make a piece of paper into 2 pieces, we need only 1 cut and to make a piece of paper into 2 equal pieces the time taken is 6 seconds which is the time taken for 1 cut. So, the number of cuts for making a paper into 10 equal pieces will be 9, so, the time taken for making a paper into 10 equal pieces will be 9 X 6 seconds=54 seconds.
