which cube if either has greater mass......... MORE?

Question

consider two cubes an aluminum cube, an iron cube that both have an edge length of 3.0 cm.

1. which cube if either has greater mass.
2.which cube displaces the more water when fully submerged?
3. which cube experiences the buoyant force of greatest magnitude when fully submerged?
4. calculate the magnitude of the buoyant force in newtons acting on the aluminum cube and the iron cube when each submerged in water.
5. if either block is immersed only half-way into the water, how does the magnitude of the buoyant force in this case compare to the buyoant forct when tat same block is fully submerged?

thank you very much for the help.

Answer 1

1. Iron is denser so has more mass.
2. Both have same volume, displace same amt. of water.
3. Both displace same volume, experience same buoyant force.
4. Fbuoy = volume * water density * g
5. Half the volume displaced ==> half the Fbuoy.
