packing peanuts are harder to do only because of the size, and density of the peanuts, its very hard to be exact with them

ABOUT how large is the box?

I would try something harder than packing peanuts, and maybe smaller, should be a lot more accurate

I have a ritual called "terminator". I crouch in the shower in the "naked terminator" pose. With eyes closed I crouch for a minute and visualize either Arnie or the guy from the 2nd movie. I then start to hum the T2 theme. Slowly I rise to a standing position and open my eyes. It helps me get through my day. The only problem is if the shower curtain sticks to my terminator leg. It sorta ruins the fantasy.

If it is all fiberglass, fill it with water. Dump the water in a round bucket and measure. That will be exact.
