The buoyant force is given by the following equation:

F_{B} = ρgV

where ρ = density of the fluid, g = acceleration due to gravity, and V is the volume of displaced fluid. In this case, the volume of the displaced fluid would be the volume of the entire submarine and the density of the fluid is the density of water. Also, since the submarine is neutrally buoyant, this means that the buoyant force trying to push the submarine out of the water is equal to the weight of the submarine itself. I hope this helps!
