To solve the problem, we need to determine the volume of the rock using the principle of water displacement. Here's a step-by-step explanation:
Step 1: Understand the Problem
The image shows two graduated cylinders:
1. The first cylinder contains 30 mL of water.
2. The second cylinder contains the same rock submerged in water, and the water level rises to 40 mL.
The goal is to find the volume of the rock.
Step 2: Principle of Water Displacement
The volume of the rock can be determined by the amount of water it displaces when submerged. The increase in the water level in the second cylinder is equal to the volume of the rock.
Step 3: Calculate the Volume of the Rock
- Initial volume of water in the first cylinder: 30 mL
- Final volume of water in the second cylinder (with the rock submerged): 40 mL
The volume of the rock is the difference between the final volume and the initial volume:
\[
\text{Volume of the rock} = \text{Final volume} - \text{Initial volume}
\]
\[
\text{Volume of the rock} = 40 \, \text{mL} - 30 \, \text{mL} = 10 \, \text{mL}
\]
Step 4: Conclusion
The volume of the rock is
10 mL.
Final Answer:
\[
\boxed{10}
\]
