Question

Calculate the density of an object whose mass is 10 kilogram and volume is 2 cubic metre​

Answer 1

Answer:

5 kg/$m^{3}$

Explanation:

Given:

Mass = 10 kg

Volume = 2$m^{3}$

Density = mass / volume

Density = 10kg / 2$m^{3}$

Density = 5 kg/$m^{3}$

Answer 2

Given :

• Mass of the object is 10 kg.
• Volume of the object is 2 m³.

To find :

• Density of the object.

Solution :

Formula Used :-

${\boxed{\bold{D=\dfrac{M}{V}}}}$

• Terms identification :-
• D = Density of the object.
• M = Mass of the object.
• V = Volume of the object.

Here ,

• M = 10 kg.
• V = 2 m³.

$\implies\sf{D=\dfrac{M}{V}}$

$\implies\sf{D=\dfrac{10}{2}}$

$\implies\sf{D=5}$

Therefore, the density of the object is 5 kg/m³.
