Referring to the three types of knowledge representation: formulas, diagrams, and text, the
knowledge hardness H can be defined by the number of formulas F, the number of diagrams T, and
the volume of text W.

H= F+T (1)
W
Where W represents the volume of text. Under comparable conditions, the volume of text is
directly proportional to the number of text pages P (where W equals P multiplied by the average
number of words per page w). By introducing a proportionality constant k, we have:
