How to find total linear distance of a part

Hello all,

I'm trying to figure out if there's a tool in Solidworks that will give me the total linear distance of any given part.  For example, if I have a part that is 11" x 5" the total linear distance is 32".  Simple, but when you start to add multiple holes and cutouts within the part that number becomes more time consuming to calculate.  Is there a diagnosis or analysis tool in Solidworks that will calculate that data for me?

Thanks in advance!
