Calculate the mass of an iron body that has a volume of 20 cm³. The density of iron is 7800 kg/m³.

1) 156 g
2) 1.56 kg
3) 15.69 kg

Answer :

Final answer:

The mass of the iron body with a volume of 20 cm³ is 156 g.

Explanation:

To calculate the mass of the iron body, we can use the equation for density: Density = mass/volume. Rearranging this equation, we have mass = density x volume. The density of iron is 7800 kg/m³, which is equivalent to 7.8 g/cm³. Given a volume of 20 cm³, we can calculate the mass by multiplying the density and volume: 7.8 g/cm³ x 20 cm³ = 156 g.
