The density of the iron is 7.85 g/cm³
Density is simply defined as the mass of a substance per unit volume of substance. It is expressed mathematically as:
[tex]Density = \frac{Mass }{Volume }[/tex]
To solve the question given above, we'll begin by calculating the volume of the iron. This can be obtained as follow:
Dimension = 3.0 cm by 3.0 cm by 3.0 cm
Volume = 3 × 3 × 3
Volume = 27 cm³
Thus, the volume of the iron is 27 cm³
Finally, we shall determine the density of the iron as follow:
Mass of iron = 212 g
Volume of iron = 27 cm³
Density =?
[tex]Density = \frac{Mass}{Volume } \\\\Density = \frac{212}{27}[/tex]
Density = 7.85 g/cm³
Therefore, the density of the iron is 7.85 g/cm³
