How many 18 x 18 craft pillows will this fill?

If I wanted to use this to stuff 6 standard bed pillows would 10lbs be enough? I’m not stuffing them very firm either.

It's enough to fill my 4x3.5 ceiling?!

I was wondering how many throw cushions will I be able to get from a 10lb box ? I am looking at 18"x18" ones.
