It looks like you've uploaded an image titled
"Volume by Water Displacement", which appears to be a worksheet or educational activity involving the concept of measuring volume using water displacement.
Since I can't view images directly, I'll explain how such a task typically works and guide you through solving it based on common formats.

🔍 What is Water Displacement?
Water displacement is a method used to measure the volume of irregularly shaped objects. When an object is submerged in water, it displaces a volume of water equal to its own volume. The amount of water displaced (in milliliters, mL) equals the volume of the object (in cubic centimeters, cm³), since 1 mL = 1 cm³.

📊 Typical Format of This Worksheet
The worksheet likely shows:
- A series of graduated cylinders.
- Each cylinder has a certain amount of water.
- Then, an object is added to the cylinder, causing the water level to rise.
- You are asked to calculate the
volume of the object based on the difference in water levels.

✔ How to Solve It
For each row (or set of cylinders):
1.
Read the initial water level (before adding the object).
2.
Read the final water level (after adding the object).
3.
Subtract the initial from the final to find the volume of the object:
\[
\text{Volume of object} = \text{Final volume} - \text{Initial volume}
\]

🧮 Example
Let’s assume one of the rows shows:
- Initial water level: 40 mL
- Final water level after object is added: 55 mL
Then:
\[
\text{Volume} = 55\,\text{mL} - 40\,\text{mL} = 15\,\text{mL} = 15\,\text{cm}^3
\]
So, the object has a volume of
15 cm³.

🎯 Instructions for Solving Your Worksheet
1. Go through each pair of cylinders (before/after).
2. Record the initial and final volumes.
3. Subtract to get the volume of the object.
4. Write your answer in the blank space provided (usually labeled "Volume = ___ mL").

💡 Tips
- Make sure to read the scale correctly (e.g., check if markings are every 1 mL, 2 mL, etc.).
- Look at the bottom of the meniscus (the curved surface of the water) when reading the volume.
- If the object floats, this method won’t work unless it's fully submerged (but usually these problems involve sinking objects).

If you can describe the specific numbers or values shown in the image (e.g., "first cylinder has 30 mL, then 45 mL after object"), I can help you solve each one step-by-step!
Would you like to do that? Just list the initial and final volumes for each case.
