Question

A block of iron of mass 1560 g has a volume of 200cm. Find the
density of iron in Sl unit.​

Answer 1

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 2

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
