My 95 doesn't leak much sound at all with no added material...

Get out a measuring tape and measure. For example, the back wall is something like 56" across and maybe 24" tall from floor to bottom of the window.
56" x 24" =1344 sq in
(12"x12"=144sq in)
1344/144=9.34 sq ft.
So the back wall needs 9.34 sq ft.
Just measure everywhere including the roof and you'll be close.
