cubic foot of wood? how big is this? damn restrictions

its whispering pines campground in upstate NY... campground is local yes...they don't allow any outside wood at all.... I guess a bunch of local campgrounds now doing this. for two nights I will bite the bullet, better then having no trees in the campground... it is a private campground... never been there.. not far from me though and full hookups.. under 20 miles from my house, so if I like it then I found a new campground that I can go to in a whim
