Density = Mass over Volume

• D = m/V

Step-by-step explanation:

Step 1: Define

D = 25 g/cm³

m = 100 g

Step 2: Solve for V

1. Substitute variables [D]:
   `\displaystyle 25 \ g/cm^3 = (100 \ g)/(V)`
2. Multiply V on both sides:
   `\displaystyle V(25 g/cm^3) = 100 \ g`
3. Isolate V:
   `\displaystyle V = 4 \ cm^3`
