SUMMARY
The discussion focuses on calculating the buoyancy force acting on a submerged iron cube with sides of 20 cm. The density of iron is established at 7860 kg/m³, while the density of water is 1000 kg/m³. The correct formula for buoyancy force is derived from the weight of the water displaced, using the equation W(DL) = (D(L))(V)(g). The initial calculation of 8x10^7 Newtons is incorrect due to dimensional inconsistencies, emphasizing the importance of using SI units for accurate results.
