[answerhappygod]

You are shipwrecked and floating in the middle of the ocean on a raft. You have a treasure chest full of gold. Your raft is barely afloat, so you have two choices on how to position the treasure chest:
1) Keep the chest on top of the raft
2) Tie the treasure chest to the bottom of the raft, so that the chest is completely submerged.
A) Which choice would cause you to displace a greater mass of water? Or, would they both cause you to displace an equal mass of water?
B) Which choice would cause you to displace a greater volume of water? Or, would they both cause you to displace an equal volume of water?
C) Which choice would cause the raft to float higher in the water? Or would they both do so?
Please explain and show your work! Thank you!
