Question

calculating the volume of an irregular solid. use the image to determine the volume of the rock. initial volume blank ml. final volume blank ml. volume of rock blank cm³

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 $cm^{3}$
