Given:-
- Mass (m) = 1560g
- Volume (v) = 200cm³
To Find:-
- Density of iron in SI units (d)
Solution:-
Firstly we converse the unit here
Mass (m) = 1560/1000 = 1.56kg
1m³ = 10⁶ cm³
∴ 200 = 200/10⁶ m³
= 0.0002m³
As we know that mass per unit volume is called density.
→. d = m/v
Substitute the value we get
→ d = 1.56/0.0002
→ d = 1.56/0.0002
→ d = 7800kg/m³
∴ The density of iron in SI unit in 7800kg/m³.

Answer:
0.0764kg/cm^3
Explanation:
=> Mass = 1560
=> volume = 200cm^3
Acceleration due to gravity (g) = 9.8ms^-2
Force = 1.56×9.8 = 15.28 N
=> density = Force/volume
=> Density = 15.28/200
=> Density = 0.0764 kg/cm^3
