Initial data: V (volume of a given copper part) = 100 cm ^ 3.

Reference data: according to the condition ρm (copper density) = 8900 kg / m ^ 3.

SI system: V = 100 cm ^ 3 = 100 * 10 ^ -6 m ^ 3.

We calculate the mass of this copper part by the formula: m = V * ρm.

Let’s calculate: m = 100 * 10 ^ -6 * 8900 = 0.89 kg or 890 g.

Answer: The mass of this copper piece is 890 grams.
