The question depends on what the aluminium is floating in. It is denser than water so will sink a block will sink in water without any pennies. If, on the other hand, it is shaped (like a boat) then the number of pennies required will depend on the shape.
Only one penny is required, if it is moving fast enough to puncture the hull. If you are talking about the weight of the pennies, then aluminum boats come in various sizes, so they do not all have the same penny carrying capacity. A ten foot long aluminum rowboat can carry a million pennies without sinking. Try it.
The answer depends on:How well the foil boat is made, andWhich country's currency.

Sink
The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float.
Aluminum powder will sink in water because it is denser than water.
i do not know the answer but i do know that once it weights 93g it will sink.
They will sink in most common fluids but not all.
Aluminum will sink in gasoline because its density (2.7g per cc) is greater than that of gasoline (about 0.7g per cc).

It will sink, but sometimes a little bit will get stuck on the surface for a little while. It will sink too if you give it a little bit of time.
Not if the pellets are solid. Aluminum will sink in water because its density (2.7g per cc) is greater than water (1.0g per cc).
A crumpled ball of aluminum will sink in water because it is denser than water. Even though aluminum can float in its solid form due to its low density, once crumpled into a small, dense ball, its overall density increases, causing it to sink.
That depends what its depth is in centimetres.
