Why would water displacement be the preferred method for determining volume, even if the object were regularly shaped (cube, cylinder,

Explanation:

Water is a standard way to determine volume because it can reach every spot in the shaped, no matter how complicated it is, it's fluency properties makes it perfect for that.

Also, the water doesn't have solid particles inside, so the volume can't change. This mean that if you use another liquid that could have solid particles, they can stuck in the walls of the shaped, so, this changed the volume of the liquid and, therefore, your measurement.
