That, my friend, rather depends on what kind of household furniture it is, what it's made from, wether or not you live on the moon etc.
not really because all furniture weighs a different amount... you would have to weigh each piece of furniture before you put it in the container.
More info needed. How much does 0.4 cubic feet of what weigh? Air? Lead? Water? Dirt?
2.5 cubic feet of water weighs about: 156 pounds.
2.25 cubic feet of water weighs about 140 pounds.
It all depends on what you have in the cubic feet. -- If the cubic feet are full of air, they weigh about 8 pounds. -- If they're full of water, they weight about 6,243 pounds (3.1 tons). -- If they're full of lead, they weigh about 70,793 pounds (35.4 tons). -- If the cubic feet are completely empty, they weigh exactly zero.
10pounds
The weight of 2.25 cubic feet of water is approx 4495 pounds-force (lbf).
Alot!!
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.
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
It depends on the density of the substance
Roughly 72 pounds.
