While the latitude in decimal degrees of Sydney, Australia is  33.8600 degrees South, its longitude is 151.2094 degrees East.  Sydney was founded in 1788 as the first Britisâ¦h colony.
Density is a measure of mass per unit of volume. Density is a measure of mass per volume. The average density of an object equals its total mass divided by its total volume. An object made from a comparatively dense material (such as iron) will have less volume than an object of equal mass made from some less dense substance (such as water). Perhaps the highest density known is reached in neutron star matter.
Three Parts:Calculating the Volume of Regular ObjectCalculating the Volume of an Irregular ObjectCalculating DensityCommunity Q&A. Volume is the amount of space an object occupies while density is the mass of an object per unit volume. You need to know the volume of an object before you can calculate its density. Calculating volume for regular objects can be done with a simple formula determined by the shape of the object. Common units for volume are cubic centimeters (cm3), cubic meters (m3), cubic inches (in3), and cubic feet (ft3). Once you have the volume, density is one more simple calculation away. Common units for density are grams per cubic centimeter (g/cm3) or grams per milliliter (g/mL).
