A 9.0 kg block of metal is suspended from a scale and immersed in water as in Figure. The dimensions of the block are 12.0 cm *9.0 cm *9.0 cm. The 12.0 cm dimension is vertical, and the top of the block is 5.00 cm below the surface of the water.

1. What are the forces exerted by the water on the top and bottom of the block? (Do not ignore the effect of the air above the water. Take P₀ = 1.0130 *10⁵ N/m².)
2. What is the reading of the spring scale?
3. Show that the buoyant force equals the difference between the forces at the top and bottom of the block.
