Step-by-step explanation:

Density is defined as the mass present in a unit volume of a substance.

Mathematically, Density =
(mass)/(volume)

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.
