I gave you two methods here. The second is quicker than the first.

First method:
inch=2.54 centimeters
inch=25 words

x=average words in centimeter
y=5.3 (average letters per word)

Divide each side by 2.54

xy=average letters per square centimeter
=average letters per square centimeter

52.2 average letters per square centimeter

Second method:
inch=2.54 centimeters
inch=25 words
5.3 letters per word

(5.3)(25)=letters per inch
132.5

Divide by 2.54 to get average letters in centimeter
132.5/2.54=52.2

52.2 average letters per square centimeter
