consider two cubes: a copper cube (Density = 8.96 g/cm^3) and a lead cube (Density = 11.4 g/cm^3) that both have an edge length of 3.0 cm.

1) which cube (if either) has the greater mass? How do you know?

2) which cube (if either) displaces more water when fully submerged? how do you know?

3) which cube (if either) experiences the buoyant force of greatest magnitude when fully submerged? How do you know?

4) calculate the magnitude of the buoyant force (in Newtons) acting on the copper tube and the lead cube when each is fully submerged in water. Show your work!

5) If either block is immersed only halfway into the water, how does the magnitude of the buoyant force, in this case, compare to the buoyant force when that same block is fully submerged?
