A cube made of Aluminum with sizes length = depth = height = L is suspended by a wire in a large vat of water as shown in the figure below. Another cube, made of Lead, with sizes length = depth = height = L is also suspended by a wire the same vat of water as shown in the figure below. The lead cube is deeper into the water than the aluminum cube. Explain each one of your answers. 

Draw one free body diagram for each cube showing all the forces acting on them (email me the graph). 

Which cube, if any, displaces more water? 

Which cube, if any, experiences a greater buoyant force?

For which cube, if any, is the tension in the wire greater?  

Which cube, if any, experiences a greater pressure on its lower face? 

Which cube, if any, experiences a greater force on its lower face? 

For which cube, if any, is the difference in pressure between the upper and lower faces greater?
