Yes, styrofoam is water resistant.
100 %
Styrofoam generally provides better insulation than cardboard. Styrofoam has a higher insulating capacity due to its closed-cell structure, which traps air and provides better thermal resistance compared to the open-cell structure of cardboard. Additionally, Styrofoam is more water-resistant, making it a better choice for insulating against moisture.

A styrofoam cup will float in water because styrofoam is less dense than water, causing it to displace water and float.
The density of styrofoam is lower: about 0.028 to 0.045 times that of water.
Styrofoam is made from polystyrene, a type of plastic that is not easily biodegradable. It can take hundreds of years to decompose in the environment, releasing harmful chemicals along the way. The structure of Styrofoam also makes it resistant to breaking down naturally.
Styrofoam floats on water, Soap sinks.
This depends on what you are trying to use to dissolve the Styrofoam. Gasoline will dissolve Styrofoam. Water will not.
Styrofoam is lighter than water, so it floats. In nature, heavy objects are more effected by gravity, so they are forced down.
The block of Styrofoam would float on the surface of the water because Styrofoam is less dense than water. Its buoyant force is greater than its weight, causing it to stay afloat.
Cotton is not water resistant.
