Problem data: V (volume of a given brass ball) = 4 cm3 (in SI system V = 4 * 10-6 m3).

Reference values: according to the condition ρl (density of brass) = 8.9 g / cm3 (in SI system ρl = 8900 kg / m3).

To determine the mass of a given brass ball, we use the formula: m = ρl * V.

Let’s calculate: m = 8900 * 4 * 10-6 = 0.0356 kg (35.6 g).

Answer: A given brass ball has a mass of 35.6 g.
