Answer:
We know that Density = Mass/Volume
Given mass of the rock = 210 g
Volume occupied by rock = 70 cm³
Therefore it's density = 210/70
Density of rock = 3 g/cm³

Answer:
3 g/cm³ or 3000 kg/m³
Explanation:
formula = mass/volume
= 210/70
= 3 g/cm³
or if u want it in kg/m³:
210g = 210/1000
= 0.21kg
70cm³ = 70 × 0.000001
= 0.00007m³
density = 0.21/0.00007
= 3000 kg/m³
