To calculate the volume of the irregular solid (rock) using the image, we need to follow these steps:

1. **Initial Volume (Before Rock is Submerged)**:
   - From the left beaker, the liquid level is at **20 mL**.

2. **Final Volume (After Rock is Submerged)**:
   - From the right beaker, the liquid level is at **30 mL**.

3. **Volume of the Rock**:
   - The volume of the rock is determined by the difference between the final volume and the initial volume:
   \[
   \text{Volume of rock} = \text{Final volume} - \text{Initial volume}
   \]
   \[
   \text{Volume of rock} = 30 \, \text{mL} - 20 \, \text{mL} = 10 \, \text{mL}
   \]

Since \(1 \, \text{mL} = 1 \, \text{cm}^3\), the volume of the rock is:

\[
\text{Volume of rock} = 10 \, \text{cm}^3
\]

Here are five related questions:
1. What is Archimedes' principle, and how does it relate to this method?
2. How can this method be applied to calculate the volume of other irregular objects?
3. What other units can be used to measure volume besides mL and cm³?
4. Why does the water level rise when the rock is submerged?
5. What factors could affect the accuracy of this volume measurement?

**Tip:** Always make sure the object being measured is fully submerged to get an accurate volume using water displacement.

Use the image to determine the volume of the rock.

Learn how to calculate the volume of an irregular solid, such as a rock, using the water displacement method. This involves measuring initial and final water levels in a graduated cylinder. Suitable for students in Grades 6-8, this method highlights key concepts in measurement and Archimedes' principle.
