# Fill the 5 liter bucket # Pour it into the 7 liter bucket # Fill the 5 liter bucket # Fill the 7 liter bucket from the 5 (2 liters go in leaving 3 liters in the 5 liter bucket) # Empty the 7 liter bucket # Pour the 3 liters from the 5 liter bucket into the 7 liter bucket # Fill the 5 liter bucket # Fill the 7 liter bucket from the 5 liter bucket (4 liters go in leaving 1 liter in the 5 liter bucket) # Empty the 7 liter bucket # Pour the 1 liter form the 5 liter bucket into the 7 liter bucket # fill the 5 liter bucket. You now have 5 liters in the 5 liter bucket and 1 liter in the 7 liter bucket; 6 liters in all. Pour the 5 liters into the 7 liter bucket if you want all 6 liters in one container.

Fill up 8 liter bucket and 5 liter bucket. Pour 3 liter out from the 5. Pour 6 liter from the 8. Add the remains from the 5l back to the remains in the 8 liter and you have 4 liters.

1)take 3liters frm 8liter bucket 2)pour thees 3 liters to the 5 liter bucket 3)take 3 liter from 8liter buket using 3 liter buket 4)pour the water frm 3 liter buket to 5 liter buket till it fills 5)pour the 5liters to the 8liter bucket 6)so we have 1liter in 3liter buket & 7liters in 8 liter buket 7)pour the one litre to the 5liter buket 8)nw take 3 liters from 8liter buket using the 3 liter buket 9)so we have 4 liters in 8liter buket 10)pour the 3 liters from the 3liter bucket to the 5 liter buket hence solved

since you're probably talking about the volume of water in the bucket, you could use either ml or liters (1 liter is 1000 ml), grams are a measure of weight and meters measure length.

Fill the 3 liter bucket, then dump it into the 7 liter bucket. Do it again, so that now you have 6 liters in the 7 liter bucket. Then fill the 3 liter bucket, and pour it into the 7 liter bucket so that you have exactly 7 liters in the 7 liter bucket. You should have 2 liters left in the 3 liter bucket................if all that made sense :P

This method works with any such problem, as long as the two buckets' liter-capacities (or gallon capacities, etc.) have no common factors, or else the common factors are also factors of the amount you're trying to measure. Fill the 7-liter bucket, and empty 5 liters of it into the 5-liter bucket; then dump out the 5 liters. Two liters will remain in the 7-liter bucket; transfer them to the 5-liter bucket. Fill the 7-liter bucket again, and empty enough of the bucket into the 5-liter bucket to fill it. That should only be 3 liters transfered, leaving 4 liters left in the 7-liter bucket. QED.

Fill up 8 liter bucket and 5 liter bucket. Pour 3 liter out from the 5. Pour 6 liter from the 8. Add the remains from the 5l back to the remains in the 8 liter and you have 4 liters.

ml 1 liter = 1000 ml 1 ml = 0.001 L

You could fill the 7-liter bucket and pour water into the aquarium until it is full, but that would make too much sense. If you really need to have three liters, fill the 7-liter bucket (which, although unmarked, will be larger than the 4-liter bucket) and pour it into the 4-liter bucket. When the 4-liter bucket is full, there will be three liters remaining in the 7-liter bucket.

pour out one litre from 5L bucket :D LOL
