Question

the Density of the material of a given object is 2800kg/m3 . Find the volume of this Object in cm3 if it's mass is 1.4kg​

Answer 1

Answer :

0.0005m³

Explanation :

Density of the object given is 2,800kg/m³ and it's mass is 1.4kg.

Finding the volume.

We know,

$\boldsymbol{ \rho = \dfrac{m}{v} }$

Where,

• p(density) = 2,800kg.
• m(mass) = 1.4kg

By the given value,

$\implies \: \boldsymbol{ 2800 = \dfrac{1.4}{v} }$

$\implies\boldsymbol{\dfrac{2800}{ 1.4}= m}$

$\implies\boldsymbol{m = \bf 0.0005m^3}$

∴ The mass of the object is 0.0005m³
