5g/cm³
it is not iron.
Explanation:
Given parameters:
Density of iron = 7.874g/cm³
Mass of metal = 2000g
Volume of metal = 400cm³
Unknown:
Density of bar = ?
Is it iron = ?
Solution:
The density of a substance is its mass per unit area. Every substance have an intensive density value that typifies them all.
The density of water and other substances are the same if they maintain their level of pureness.
Density = 
Density of metal bar =
= 5g/cm³
Since this value is not the same as the given density of iron, it is not iron.
