A solid cube of side length $$L$$ and density $$\rho_1$$ is submerged in a fluid of density $$\rho_2$$, where $$\rho_1 < \rho_2$$. If the cube is then placed in a different fluid of density $$\rho_3$$, where $$\rho_3 = \rho_1/2$$, what happens to the buoyant force compared to the first fluid?

If the area is halved while force remains constant, what is the effect on pressure?
