(image of a graduated cylinder with a rock inside, water level near 30 ml markings)

Explanation:

Step1: Read final water volume

The graduated cylinder shows a final volume of $34.0\ \text{mL}$.

Step2: Calculate rock volume

Subtract initial water volume from final volume.
$\text{Volume of rock} = 34.0\ \text{mL} - 20.0\ \text{mL}$
Since $1\ \text{mL} = 1\ \text{cm}^3$, the volume in cubic centimeters is equal to the volume in milliliters.

Answer:

$14.0\ \text{cm}^3$ (or $14.0\ \text{mL}$)
