According to the box it has 20 sq ft in each one and I used 2 boxes of it to cover the floor and up the back wall to the window and both doors and up to the fire wall in front. I left the factory stuff in place on the fire wall. I have 2 12" peices left in the second box. That would mean 38 sq ft is what I used. I didn't cover every inch of the floor are the back wall but I did a pretty good bit!
