Answer:

The answer is 1.89 kg

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 9 kg/m³

1 cm³ = 0.000001 m³

210,000 cm³ = 0.21 m³

So we have

mass = 9 × 0.21

We have the final answer as

1.89 kg
