A Math Question: Buoyency

Woah, you all rock! Thanks a ton, I've now got my dimensions all done for a lexan box I'll be making to float in my pool with some sweet lights (FRC green cathodes). The box will measure 14" long by 5" tall by 10" wide. This should be slightly less than twice the buoyancy that I need, which should also give me plenty of room to put in all the electronics. I'll probably upload some pictures once I finish building the thing.


Thanks for the help!
