Answer:


2 g/cm^3, it will sink

Step-by-step explanation:

The density of an object is given by


d=(m)/(V)

where

m is the mass of the object

V is its volume

For the body in the problem, we have

m = 4 kg = 4000 g


V=2000 cm^3

Therefore, its density is


d=(4000)/(2000)=2 g/cm^3

And the object will sink in water, because its density is larger than that of water, which is
1 g/cm^3. (an object sinks when its density is larger than that of water, otherwise it floats).
