Help me with my science homework? Inertia, mass, density, etc?
Ok, so this is the lab/experiment:
You are going to make boats from aluminum foil to see how many stoppers they can support before sinking. You are using pieces of aluminum foil 15 cm x 15 cm long to create a boat that will float in the tub. The stoppers are 5.1 grams each, the density of the aluminum foil is 2.
My questions:
1)Suppose your lab partner creates two boats from two identical pieces of aluminum foil. The volume of boat one is 500 cm3 and the volume of boat two is 400 cm3. Which of these boats will be able to support more mass before sinking? Explain your answer.
I'm thinking "what..?" I really have no clue. So can you tell what I do to find out this answer? Please and thank you.
2) How does inertia play a part in this experiment?
This I also have no clue about, so could some one explain it to me?

1) surface area is the factor tested, the 500 cm3 would be better, like when you are in a pool, do you float better on ur back or curled in a ball?
2) intertia is a law meaning, something in motion will keep moving in a straight path and wont change until a force acts upon it. same with staying in place (An object at rest will remain at rest until acted upon by an outside force)
the boat wants to keep floating on the water once it is set there, and the stoppers are acting on it to make it capsize and sink.
