Dodecahedron Pyramids

Hi all,

I am relatively new to Solidworks, and am trying to make a dodecahedron assembly, out of 12 pentagon based pyramids. I am having trouble getting these pyramids perfectly dimensioned.

 

I am lofting the pentagon to a point a specified height above the pentagon. I have followed this site to get the distance between pentagon and point. Mathematical Misfits - three-dimensional solution | plus.maths.org

 

I entered my answer to 15 decimal places yet I am still getting something wrong. The side length of my pentagons is 22mm, is there a better way to go about this?

 

thanks for any advice
