Oh, dude, something that weighs 1000 pounds? That would be like a small car, a grand piano, or my collection of empty pizza boxes. Just your average everyday stuff, you know?
To solve this problem, we need to understand the concept of buoyancy. When the bucket is half-filled with water, the water exerts an upward buoyant force equal to the weight of the water displaced. Since the weight of the half-filled bucket is 30kg, the weight of the water in the bucket is 30kg. This means the weight of the empty bucket is 20kg (50kg - 30kg = 20kg).
Pounds are a unit of weight and centimeters are a unit of length. We can't convert one to the other. Something that weighs 160 lbs will have dimensions, but the dimensions of 160 pounds of lead will be vastly different from the dimensions of 160 pounds of feathers.
The weight per US gallon of water at 25 C is 8.33 pounds [per gallon. 2 gallons of water would weigh 16.66 pounds plus the weight of the bucket itself.
