Which glass holds the most water?
When evaluating which glass holds the most water, we have to look at the fundamental physics principle of volume displacement.
All four glasses are identical in size and are filled to the exact same water level. However, each glass has a different everyday object submerged inside it. According to Archimedes’ principle, when an object is submerged in water, it displaces an amount of water equal to its own volume.
Therefore, the glass containing the object with the smallest physical volume will require the most actual water to reach that fill line.
Evaluating the Submerged Objects
To find the correct answer, let’s look at the relative volume (the amount of space the object takes up) for each item:
