Step-by-step explanation:
Density is defined as the mass present in a unit volume of a substance.
Mathematically, Density =
Since, density is proportional to mass. So, more is the mass of an object more will be its density and vice-versa.
It is known that density of water is 1 g/ml. And any substance that has more density than water will sink into water when added to it. Whereas a substance that has less density than water will float in water when added to it.
Out of the given options density of a styrofoam cup is the least.
Hence, we can conclude that styrofoam cup is likely to float in water.
