The volume of the steel bar is 430 cm3. Find its mass.

Data: V (volume of steel bar taken) = 430 cm3 (430 * 10-6 m3).

Reference values: according to the condition ρс (steel density) = 7800 kg / m3.

The mass of the steel bar taken will be equal to the product of its volume and the density of the steel: m = ρс * V.

Calculation: m = 7800 * 430 * 10-6 = 3.354 kg.

Answer: The mass of the steel bar taken is 3.354 kg.
