Question

ILM You have a chocolate bar that consists of 5 rows. Each row contains 4 square pieces, making it 20 pieces of chocolates for eating. What is the least number of clean snaps necessary to break the chocolate bar into 20 individual pieces?​

Answer 1

Answer:-

The solution to this puzzle is really pretty simple - but, as usual with maths, only if you think about it the right way!

Each snap creates exactly one extra piece, therefore to break a bar with K squares of chocolate into all its constituent pieces will require K-1 snaps. So if the block has n rows of m pieces, it will take nm-1 breaks.

And that's all there is to it!
