Theoretically, there is no limit to the amount of weight a cubic foot could hold. At the moment of the Big Bang, the entirety of space certainly fit into a much smaller area. On the other hand, a cubic foot in a vacuum has no force of any kind at all.
Weight is actually a unit of force, which is equal to mass times acceleration. (F=ma) Weight is equal to one's mass times the acceleration due to gravity. In SI units, the number of Newtons (N) equals the number of kilograms (kg) times the acceleration due to gravity (on Earth approx. 9.81 meters per second squared, or 9.80665 m/s2).
Since your question is in feet, using the pound-mass (lbm), the imperial/US customary/international avoirdupois pound (legally defined to eight figures as exactly 0.45359237 kg), and a pound-force (lbf) equal to 1, we divide by mass in the equation F=ma to get a=F/m.
This gives us an acceleration of the standard gravitational field (gn) of 32.174 049 ft/s2.
We could also look at this from the viewpoint of atmospheric pressure on a square foot.
A foot has 12 inches, so a square foot has 122 inches2, or 144 in2.
The atmospheric pressure (atm) in pounds (lb) per square inch (in2) is 14.69595 psi.Multiplying this by 144 in2 yields 2116.2168 lbf, in units of pound-force.
Furthermore, if we divide by the acceleration of the standard gravitational field (gn), we have 65.774028 lbm.
Even if that didn't help at all, the answer to your question comes from the first paragraph:
1 cubic foot can hold any amount of mass from 0 to the mass of the universe.

How much does 57 cubic feet of water weigh?
The weight of any volume of water will depend on the gravitational force acting upon it. 57 cubic feet of water would weigh nothing in a spaceship, for example.
How much does 9 cubic feet of fresh water weigh?
Roughly 72 pounds.
How much does 0.4 cubic feet weigh in pounds?
The weight of 0.4 cubic feet depends on the density of the material. To convert volume to weight, you need to know the specific density. If we assume an average material density of 100 lbs/cubic foot, then 0.4 cubic feet would weigh 40 lbs.
