Question

Without placing an object in water, how can you determine if it will float?

Answer 1

Maybe by testing its density? Depending on what the object is, or what its made of, you might be able to hypothesize what sinks or what floats. Hope this helps! :)

Answer 2

By finding it's density $(Density= mass / volume)$ and than comparing it to the waters density (997 kg/m³).

If the density of the object is lower than the waters, it will float, otherwise, it will not.

Hope it helped,
