If the relative density of a metal is 19,what will be the mass of 20cm of the metal when immersed in water?

The mass of 20 cm of the metal is 360 grams.

Explanation:

Relative density or specific gravity is the ratio of the density of a substance to the density of a standard; usually water for a liquid or solid, and air for a gas. It has no units.  

Given, relative density of a metal is 19 and volume of the metal is 20 cm.  

We know that, Mass= Volume X Density. So, mass is 19 X 20= 380 grams.  

So, weight in water = true weight- upthrust

Desired answer is 380- 20 X 1= 360 grams.

where's the following? you gotta add it to know what the choices are
