A soy sauce bottle with a cylindrical body and a volume of 750ml. There is half a bottle of soy sauce in the bottle. When the bottle is placed upright, the liquid level of soy sauce in the bottle is high14cm; There are 500ml of soy sauce in the bottle.

It's very simple. When the bottle is placed upside down, 14 cm, and the empty part is 7 cm, then the bottle is always * * * 2 1 cm high.

Therefore, the volume of liquid in the bottle accounts for 14/2 1 2/3 of the total volume, and the bottle is 750 ml.
