How to determine the mass of a steel part with a volume of 120 cm?

Since the volume of the steel part is known and the density of the steel is a reference value, the mass of the part can be found using the formula:

m = ρ * V, where ρ is the density of the steel (ρ = 7800 kg / m3), V is the given volume of the steel part (V = 120 cm3 = 120 * 10-6 m3).

Let’s calculate the mass of the steel part:

m = ρ * V = 7800 * 120 * 10-6 = 0.936 kg = 936 g.

Answer: The weight of the steel part is 936 grams.
