According to my old RN Diving Manual, the density of "average" seawater is
1030kg per cubic metre, which would be 1.03kg per litre (cubic decimetre).
One cubic foot = 28.32 litres, so that would weigh about 29kg or about 64.3
pounds.
There are roughly 3.79 litres in a US gallon. Calculation of the weight of
a gallon of seawater and number of gallons in a cubic foot is left as an
exercise for the student...
Or go metric and use the 1 litre can support 1 kilogram rule of thumb.

Greetings:
Well, here's the old one with another bit 'o cranial flatulence!!!
Want to build a floating dock over some 30 or 55 gal plastic drums. They
will
be connected by a manifold of hoses to an air compressor thereby enabling
me
to submerge or float it like a drydock.
Got all the details worked out, but require the following info:
1. Weight of one cu. ft. of saltwater and weight of one gal. of saltwater.
2. Cu. ft. per gallon or gallons per cu. ft. of saltwater.
Knew I shoulda stayed in school!!!
