Question

Calculate the mass of a body whose volume is 2m3 and relative density is 0.52 ?​

Answer 1

Given :-

Volume of the body = 2 m³

Relative density= 0.52

To Find :-

The mass of the body.

Solution :-

We know that,

• RD = Relative density
• m = Mass
• d = Density
• v = Volume

Using the formula,

$\underline{\boxed{\sf Relative \ density=\dfrac{Density \ of \ body}{Density \ of \ water} }}$

Given that,

Relative density (RD) = 0.52

Density of water = 1000 kg/m³

Substituting their values,

⇒ 0.52 = d/1000

⇒ d = 0.52 × 1000

⇒ d = 520 kg/m³

Using the formula,

$\underline{\boxed{\sf Mass=Density \times Volume}}$

Given that,

Density (d) = 520 kg/m³

Volume (v) = 2 m³

Substituting their values,

⇒ m = d × v

⇒ m = 520 × 2

⇒ m = 1040 kg

Therefore, the mass of the body is 1040 kg.

Answer 2

Answer:

Given :-

• Volume = 2 m³
• Relative Density = 0.52

To Find :-

Mass of body

Solution :-

As we know that

Relative Density = Density of body/Density of Water

0.52 = Density of body/1000

D = 0.52 × 1000 = 520 kg/m³

Now,

Let's find Mass of body

$\huge \bf \: Mass = Density × Volume$

Mass = 520 × 2

Mass = 1040 kg

Therefore :-

The mass of body is 1040 kilograms.
