∙ 10y agoThe 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.

∙ 10y agoOnly 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.
No, aluminum does not sink in gasoline. Aluminum is less dense than gasoline, so it will float on top of the gasoline rather than sinking.
They will sink in most common fluids but not all.
Aluminum powder is denser than water, so it will sink when placed in water.

No, aluminum pellets will sink in water since aluminum is denser than water.
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.
Generally speaking, a denser substance will sink in a less dense substance. Assuming standard temperatures, since aluminum has a density of about 2.7 grams per cubic centimeter and water only has 1 gram per cc, aluminum would sink. A thin aluminum foil could float by virtue of the surface tension on water (but if submerged, will sink). An aluminum boat would float because it displaces a greater mass of water than its own weight. An aluminum block could also float on a liquid of higher density than the aluminum.
