Grid resolution and terrain analysis

Hi there! 

I want to calculate the ideal grid size for a contours_area.shp layer. 

I will use one of Hengl's formula for calculating grid resolution.

To get the grid resolution the area Hengl's formula states that I should divide the total size of the study area and
the total cumulative length of all digitized contours.

How do I determine the total cumulative length of all digitized contours?
