A farmer needs 8 gallons of water. He has only three unmarked buckets, two 6 gallon and one 11 gallon bucket.

How can he collect 8 gallons of water using three unmarked buckets? Provide solution with minimal water wastage.

The contents of one of the 6 litre buckets could be exactly divided into half if it was cylindrical or even cuboidal(like some buckets are).this could be achieved by pouring out water till the water level just reveals the bottom edge(in case of a cuboid-along one of the longest diagonals).
this is because the diagonal divides the volume of the bucket in half.
