given,
mass of the object = 50 grams 
volume of the object = 20 cm³
density of water = 1 g/cm³
now density of the object , 
density = mass / volume 
= 50 / 20 
= 5 / 2 = 2.5 g/cm³
therefore density of the object = 2.5 g/cm³ 
and since ,
density of the object > density of water 
2.5 > 1 
therefore the object will sink in water .
                i hope it helps......................................^_^

The object will sink since it has a density more than that of water
