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
