A hollow plastic toy has a mass of 6.0 g and an outer volume of 35 cm3.
There is a small crack in the toy's casing.
The toy is placed in a container of water. Water slowly leaks into the toy through the crack without changing its outer volume, and eventually the toy sinks.
The density of water is 1.0 g/cm3.
Which mass of water has entered the toy when the top of the toy is first level with the water surface?
