To calculate population density, two pieces of information are needed: the total population of a specific area and the land area of that same area. By dividing the population by the land area, population density can be determined, usually expressed as the number of individuals per square unit (e.g., individuals per square mile or individuals per square kilometer).

try reading a bible and figure it out. good luck!
It means: * Calculate the density of an object * Calculate the density of its pieces * Compare
you need to know its mass (weight) and volume; density is mass/volume
If you need the radius, you might try to figure it out based on other pieces of information.

Yes, a crayon has greater density than pieces of crayon, assuming the pieces are not heated and mashed together. That's because the crayon has density X and air has a lower density Y. Some combination of X and Y will always be less than X.
If a cube of jello is cut into two pieces the density of the pieces do not change.
