How much material should I order?

Hi guys - going to replace the interior insulation.  Anyone have any idea how many square feet to order?  The material usually comes in rolls of 48 inches. 

 

Thanks and take care

I ordered 10ft for my "E" and had about 4sq.ft remaining. My guess would be 12 running ft will get the job done.
