Well, from fluid dynamics, we know that the mass displaced is equal to. So the mass displaced or the mass of the fluid that is displaced by that object is equal to the product of the mass of that object multiplied by the ratio of the density of the fluid to the density of that object. So let's call it a particle. Now, let's, let's represent the bar, because that is used in this equation. The bar is equal to one divided by the density of the particle. And if this is how we want to represent the density of the particle, then we can basically rewrite the following equation in the following way.
