calculating the volume of an irregular solid. use the image to determine the volume of the rock. initial…

Explanation:

Step1: Determine initial volume

Read the initial - liquid level in the graduated cylinder. The initial volume of the liquid is 20 ml.

Step2: Determine final volume

Read the liquid - level in the graduated cylinder after adding the rock. The final volume of the liquid and the rock is 30 ml.

Step3: Calculate volume of rock

The volume of the rock is equal to the final volume minus the initial volume. So, $V = 30 - 20=10$ ml. Since 1 ml = 1 $cm^{3}$, the volume of the rock is 10 $cm^{3}$.

Answer:

Initial volume: 20 ml Final volume: 30 ml Volume of rock: 10 $cm^{3}$
