To solve this problem we will apply the concepts related to the Pascal principle for which the balance of Forces between the Buoyancy Force and the body weight is defined.
We define the weight of the body in the international system as


At the same time, the force caused by seawater as

Note: Remember that the definition of density tells us that

Here,
m = mass
Density
V = Volume
g = Gravity
As a reaction force is the buoyancy force then


If the body is in balance then the balance of forces tells us that








Therefore the total water displaced is
