square footage of K5 Blazer flooring?

[riz]

I'm about ready to install Dynamat material in my 82 K5 Blazer and was wondering if any of you knew the square footage of the entire floor area so I can buy enough sound deadener. My Blazer is in storage right now so I can't measure myself. It is currently completely gutted so once I get it out of storage I will be installing the mat. I want to cover as much floor area as possible including the front floor boards as well as the entire rear floor. Would that be overkill to cover the entire flooring? Any help with getting very close measurements would be greatly appreciated.
