Sailin' steve likes to test the buoyancy of different objects. he threw a spherical object into a fluid that has a greater density than the object does. he also threw a square object into the fluid that has a greater density than the fluid. predict which object will float best

Spherical object will float.

Explanation:

Density may be defined as the mass of an object per unit of the volume. The S.I. unit of density is Kg/m^3. The density of an object decides whether it float or sink in the object.

The object that has greater density than water will sink in the water. The object that has less density than water will float in the medium. Here, the spherical object is less denser than the fluid in which it is immersed so it will float in the water.

Thus, the spherical object floats in the water.
