Water is 64# per cubic foot.

How'd you arrive at that? 'Cuz I'm driving myself nuts here trying to
convert lbs/gal (8.333) to lbs/cu.ft. and it's not working.

Bill, I think, is using the weight of salt water, which is 64# per
square foot, but close enough. Fresh PURE water is 62.5 pounds per
cubic foot, and there are 7.5 gallons per cubic foot.
(8.33333x7.5)=62.5 (rounded!)
