If your bar is 3 chunks wide and 5 chunks long, how many cuts do you need to make so that you have all individual chunks?
A slice means one straight-line cut with a sharp knife. You may not stack pieces on top of, or next to, each other in such a way as to cut through multiple pieces with one cut.
In general, if a bar of chocolate is n chunks wide and m chunks long, how many cuts (as described above) would you need to make in order to separate it into individual pieces?
