SUMMARY
The problem involves calculating the volume of a metal block that weighs 9N in air and 7N in water, resulting in a correct volume of 200 cm³. The solution utilizes the principle of buoyancy, where the difference in weight (2N) corresponds to the weight of the water displaced by the block. By applying the equation for buoyancy and the density of water, the volume can be derived directly from the weight difference.
