How does the milk bottle work?
There are several ways you could determine the capacity of a
milk jug:
1: Fill the milk jug with water and then transfer the water to a
graduated measuring jug
2: take a bottle of known volume such as a soda bottle. Fill the
soda bottle and transfer its contents to the milk jug to get its
approximate capacity
3: weigh the empty milk jug and make a note of the weight. Then,
fill the milk jug with water. 1 cubic cm of water weighs 1 gram.
Deduct the weight of the empty jug from the weight of the full jug
to give the weight of the water inside. If, for example, the water
weighs approximately 1000 grams then you have a 1 litre milk
jug
