¡Hellow!
How we know, for calculate density, we can use the formule:
[tex]\boxed{\textbf{p = m / v} }[/tex]
Where:
[tex]\sqrt{[/tex] p = Density = ?
[tex]\sqrt{[/tex] m = Mass = 57,9 g
[tex]\sqrt{[/tex] v = Volume = 3 cm³
Let's replace according we information:
p = 57,9 g / 3 cm³
p = 19,3 g/cm³
The density of the metal bar is 19,3 g/cm³.
¿Good luck?
