volume= 2000 cm3
or 2000 x 10⁻⁶ m₃ or 2 x 10⁻³ m₃
density= 70 kg / 2 x 10 ⁻³
= 5 x 10 ³
relative denisty= denisty of substance/ water density
= 35 x 10³ / 10³
=35
or 2000 x 10⁻⁶ m₃ or 2 x 10⁻³ m₃
density= 70 kg / 2 x 10 ⁻³
= 5 x 10 ³
relative denisty= denisty of substance/ water density
= 35 x 10³ / 10³
=35

➧ Volume = 2000 cm³
➾ 2000 x 10-⁶ m³
➾ 2 x 10³ x 10-⁶ m³
➾ 2 x 10-³ m³
➧ So, density of the substance
➾ 70 kg/ 2 x 10-³ m³
➾ 35 x 10³ kg/m³
➧ Relative density = density of substance / density of water
➾ 35 x 10³ / 10³
➾ 35 ...✔
