Ron now has a 6 by 13 chocolate bar and his goal is to split it into a 1 by 1 square for his family. This means that we need to look for the area!
Although we don't stop there. We might be tempted to assume that the product of 6 and 13 is the answer, but we need to consider that, for the last two remaining squares, Ron will only need to break the bar once, therefore only having to break the chocolate bar one less than its area.
With that in mind, the answer will simply be [tex]Area-1=6*13-1=78-1=77[/tex].
Answer: 77 times!
If you still don't get it, think small! Notice that, for a chocolate bar 2 squares high and 2 squares long, you will only need to break it 3 times in order to have individual squares. The same thing applies for the problem.
