That really depends on the bucket, but it would be measured kilograms.

either, depending on the sze of the bucket really
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).
# Start with empty buckets, and carry them to the well. # (Note that the larger is the 7-gallon bucket, and the smaller is the 4-gallon bucket.) # Fill the 4-gallon bucket with water to the top. # Empty all the water from the 4-gallon bucket into the 7-gallon bucket. # (Note that there is room in the 7-gallon bucket for exactly 3 more gallons.) # Fill the 4-gallon bucket again. # Pour from the 4-gallon bucket into the 7-gallon bucket all the water that will fit, spilling none. # (Note that since there was room for only 3 more gallons in the 7-gallon bucket, you now have 1 gallon left in the 4-gallon bucket.) # Dump out all the water from the 7-gallon bucket. (Pour it back into the well or onto some flowers so it's not wasted.) # Pour the 1 gallon of water that remains in the 4-gallon bucket into the empty 7-gallon bucket. # Refill the 4-gallon bucket completely. # Pour all the 4 gallons from the 4-gallon bucket into the 7-gallon bucket. # (Note that since the 7-gallon bucket had 1 gallon already and you added 4 gallons, you now have 5 gallons of water in the 7-gallon bucket!) # Bring back your 7-gallon bucket that's holding exactly 5 gallons of water. (Bring your 4-gallon bucket back too, in case you want to play again!)
1235g because 720 + 5 and a half = 720.5 = 1.235kg = 1235g
It depends on the bucket being used. Check the bucket because it might say how many litres the bucket can hold
