This is a tricky question. First you have to break the whole bar horizontally 7 times (because it is 8 pieces high). After that you will have 8 rows of chocolate with 9 pieces each. Then you will have to break each row 8 times. Finally you will have individual squares. So : 7 + 8 * 8 = 7 + 64 = 71 Answer: A) 71.
