How can you tell if something will float in water the density of water = 1g/cm³ at 20°c answer: compare the density of the object in question to the density of water if its density is less than water, it will float for example, oak floats because its density is 07 g/cm³ if the density of an object is greater than water, it will sink.
Assume a us coin is cylindrical, with use the following specifications from the us mint for coins presently in production for 2014 united states mint annual sets ( coin_specifications) to calculate the volume and density of each type of coin denomination cent. We use water as sort of a standard for density we say water has a density of 1 if something weighs twice as much as the same volume of water we say its density is two this is really handy for figuring out all sorts of things like if something will float or not anything that has a density less than 1 floats anything that has a.
