The synonym of "the original"

The volume of a bucket is 24 cubic decimeters, the bottom area is 7.5 square decimeters, and there is a hole 0.7 decimeters away from the bucket mouth. Now the bucket can hold water at most______ Kg. (1 kg per cubic decimeter of water)

Now this bucket can hold water: 1 × (24-7.5 × 0.7), = 1 × (24-5.25), = 18.75 (kg); answer: now this bucket can hold water up to 18.75 kg. So the answer is: 18.75
