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.
