Hi ARsygo,

Yes, it´s a class 3 number as well described below by Cloudy176.

To obtain this number you must understand the "Creation process" section as described in the post about the number. The most important thing is be able to understand that you must divide the surface area of Earth by the thickness of the paper to obtain the width and so calculate the number of digits.
