Make the surface area as big as possible. You can just fold the edges up so it looks like a square plate with its edges folded up.
it can hold 50 pennies depending on the base of the boat and also depenidng on the sides now if you have a 20 by 20 then may be a 100 or 150 pennies it may hold
A design with a wide base and tall walls is desirable for an aluminum foil boat. You want enough surface area supporting the pennies so they will keep floating and to not compromise that for wall height to keep water from enter your vessel.
circle boat
It depends on its size and shape.
An aluminum foil boat floats because it is more dense than water, therefore the surface tension of the water is able to hold the boat up.
a circle boat, because circles have a larger area
I have no idea this was my q i really need to know so if you know the answer please undo my answer.thx :)
maybe add food coloring
35 pennies
30 pennies
I would think a canoe or a cruise boat because a canoe can keep level while a triangle or other shapes might tip over due to unbalance. However a cruise-ship is deep and would hold more pennies.
A half gallon jug can hold about $25.00 in pennies. (:
