These tasks: m (mass of the part made of the metal being determined) = 1400 g; V (part volume) = 200 cm3.
The density of the metal from which the taken part was made is determined by the formula: ρ = m / V.
Calculation: ρ = 1400/200 = 7 g / cm3 or 7000 kg / m3 (the resulting value corresponds to the density of cast iron).
Answer: The taken part was made of cast iron with a density of 7000 kg / m3.
