A bottle, like the one shown, is filled with water up to a height of 10cm. The total height of the bottle, from the bottom to the cap, is 20cm.

When the bottle is inverted (with the cap facing down), the water occupies a height of 15cm.

Can you figure out what volume of the bottle is filled with water?
