Answer 1

Math.Round(density); //for rounding

Math.Ceiling(density); //for round up or ceiling.

Answer 2

Andrius Savčiukas ,

to round to 2 decimal places we can use:

Console.WriteLine(Math.Round(4.412761, 2));

the last argument in Round() function defines the decimal places to round

Answer 3

Where ever you want...!
Ex:
Console.WriteLine("When your mass is "+mass+" and volume is "+volume+" density = "+Math.Ceiling(density)+" kg/m^2 or "+Math.Ceiling(density/10)+ " g/cm^2");
