To determine the volume of the rock, we can use the water level readings from the graduated cylinders you mentioned.

1. **Initial Volume of Water**: This is the water measurement in the first graduated cylinder before adding the rock. It is given as 20 milliliters (mL).

2. **Final Volume with Rock**: This is the water level in the second graduated cylinder after adding the rock, which is 32 milliliters (mL).

3. **Volume of Rock Calculation**: To find the volume of the rock, we subtract the initial volume from the final volume:

\[
\text{Volume of Rock} = \text{Final Volume} - \text{Initial Volume}
\]

Plugging in the values we have:

\[
\text{Volume of Rock} = 32 \, \text{mL} - 20 \, \text{mL} = 12 \, \text{mL}
\]

Since 1 mL is equivalent to 1 cm³, we can conclude that the volume of the rock is:

\[
\text{Volume of Rock} = 12 \, \text{cm}^3
\]

So to summarize:

- Initial volume: 20 mL
- Final volume: 32 mL
- Volume of rock: 12 cm³
