Question

Calculate the mass of a body whose volume is 3 m^3
and relative density is 0.75.
[Ans. 2250 kg]​​

Answer 1

$<marque>$

GIVEN :-

Volume (V) = 3 m³.

Relative Density (RD) = 0.75.

TO FIND :-

The mass of The body .

SOLUTION :-

As we know that,

➺ Density of water = 1000 kg/m³.

➺ Relative Density = Density of body/Density of water.

Substitute The given Values,

➺ 0.75 = Density of body/1000 kg/m³.

➺ Density of body = 1000 kg/m³ × 0.75

➺ Density of body = 750 kg/m³.

❏ Hence the Density of object is 750 kg/m³.

As we know that,

➺ Mass of body = Density × Volume

Substitute the Given values,

➺ 750 kg/m³ × 3m³

➺ 2250 kg.

❏ Hence the mass of body is 2250 kg.
