density= mass/volume
The best strategy in that situation would be to use what you do know.
Object's density = (its mass) divided by (its volume)
Density is mass per unit volume; in metric system it is grams per cubic centimeter; in the English system, we use the term as weight per unit volume, or pounds per cubic inchAnother AnswerIn the SI system, the standard unit of density is the kilogram per cubic metre. The SI system doesn't use centimetres.
Then you would really be talking about a different type of unit, that (a) has nothing to do with density as it is usually defined (therefore you better give it a different name, to avoid confusion), and (b) may have no practical use.
Many countries use a penny as a minor currency unit and it is likely that each one of these has a different density.
mass/volume
The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.
square kilometers
The best strategy in that situation would be to use what you do know.
Time and distance.
cc (cubic centimeters) is a unit of volume lb (pounds) is a unit of mass (more accurately weight, but that's trivial) you would need to use the density of the substance and use the formula: density = mass / volume
mass/volume
Object's density = (its mass) divided by (its volume)
Density is calculated as measured mass per unit volume. Milliliters are a unit of volume, so you could use that in your volume measurement.
'Density' is not a unit at all. Density is how tightly atoms in an object are packed together. Therefore, density isn't a new unit, or a unit at all for that matter. The SI units of density are kg m-3. It common use the cgs unit g cm-3 is much more prevalent.
Density can be expressed as (any unit of mass) divided by (any unit of volume). My personal favorite is [ slug per hogshead ] .
