Answer 1

Given:-

• Mass of iron (m) = 1560g

• Volume (v) = 200cm³

To Find:-

• Density of iron (p)

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.
