friction and upthrust

A cubical box submerged in a container which is filled with a liquid of density $2000\text{kg/m}^3$ such that its opposite faces touches the container.If one-fourth of the box is submerged in the liquid then the force acts on one face of the box(which is in contact with the container) by thecotainer in newton is given:weight of box is $50$ N Density of box is $5000\text{kg/m}^3$ coefficient of friction between the surfaces is $0.5$ acceleration due to gravity is $10\text{m/s}^2$ neglect surface tension.
