Question

I really need some serious help with regaining my physical science credit for high school, im a sophomore.

Answer 1

Ashlie,

 

Density is simply the total mass of an object divided by the volume that the object occupies.  In your example you have an object of mass 30 grams which occupies a volume of 10 cubic centimeters (cm³).

 

So the density μ= mass ÷ volume is (30 g)/(10 cm³) = 3 g/cm³, which is read as "3 grams per cubic centimeter).

 

The Greek letter μ (mu) is commonly used to represent density.
