Density = Mass over Volume

D = m/V

<h3>Explanation:</h3>

<u>Step 1: Define</u>

D = 25 g/cm³

m = 100 g

<u>Step 2: Solve for </u><em><u>V</u></em>

Substitute variables [D]: $\displaystyle 25 \ g/cm^3 = \frac{100 \ g}{V}$
Multiply <em>V</em> on both sides: $\displaystyle V(25 g/cm^3) = 100 \ g$
Isolate <em>V</em>: $\displaystyle V = 4 \ cm^3$
