****Really think there is a mistake in my textbook. Please check**

Hey,

this specific equation we are to figure out requires us to use sampling methods, and then to calculate a bunch of different equations, however before the equation I noticed my text book has a mistake. Please correct me if im missing something.

Each sample square is 3cm by 3cm, which would = 9cm squared.

The number of characters per sample square is: 96.83

Now, to find how many characters per each square cm, the text book says to divide by 6 ? huh?

Would you not divide by 9, to get the number of characters for each square cm if its 9 square cm's?
