Here's a simple explanation:
Density = mass/volume
mass = how much "stuff" something is made of (not to be confused with weight which your mass times the force of gravity)
volume = how much space the "stuff" takes up

density is the quantity of mass consistent with unit of quantity and has units jointly with g/cc or lbs/in^3. each and every each and every now and then particular gravity is improper for density in spite of the incontrovertible fact that this is not. particular gravity is a ratio of the density of an merchandise over the density of water and subsequently has no units.

It is the ratio (relationship expressed as a fraction) between the volume of a substance and its mass (not weight).
If you have a cube that has an edge measurement of 3cm and its mass is 27g then it has a density of 27g/27cm^3 or 1g/cm^3 (1 gram per cubic centimeter). If the same size cube has a mass of 54g then it has a density of 54g/27cm^3 or 2g/cm^3. The second cube of course has a higher density.

Density is the amount of mass that an object has per unit volume. So an object that is 1 cubic foot and weighs 100lbs, it is more dense than an object that is the same size and weighs only 50lbs.
Think of a grocery bag filled with rocks vs a grocery bag stuffed with feathers. They take up the same amount of space, but the bag of rocks is way heavier and more dense.

Density is a measure of mass over depth. It tells us how compacted together an object is (or how much matter is "stuffed" in space).
You derive a density by dividing units of mass by units of volume.
Unit(s) of Mass/Unit of Volume
e.g.
grams/cubic mililiter (g/mL^3)
read "grams per cubic mililiter"
Let's say a pebble's density is 5 g/mL^3. Something that is twice as dense would have a density of 10 g/mL^3.

Density is how much things weigh.
The basic density is that of water,it has a density of 1.
Lead has a density of 13,which means that the same volume of lead will weigh 13 times what that volume of water weigh.
The number assigned to every thing is called the "coefficient of density".

Density is equal to mass per unit of volume or more simple mass/volume

each things has it own density.
density of water : 1 g/ cubic cm
density of sea water : 1.03 g/ cubic cm
if density of a things more than 1 g/cubic cm it will sink
if density of a things less than 1 g/cubic cm it will float...
basic equation:
density :: Mass/Volume
Mass :: density * volume
Volume :: Density/Mass

it is day light out and you are going to enter a forest as you go into the forest the amount of sunlight that u see is changing, the deep you go into the forest the darker it get and the forest is producing density that blocks out the sun light
