To solve this problem, we need to determine the volume of the irregular object (the rock) using the
water displacement method.
Step-by-step Explanation:
1.
Identify the starting volume:
- The first graduated cylinder shows the initial volume of water before the object is added.
- From the image:
Starting Volume = 50 mL
2.
Identify the ending volume:
- The second graduated cylinder shows the volume after the irregular object is submerged in the water.
- From the image:
Ending Volume = 75 mL
3.
Calculate the volume of the object:
- The volume of the irregular object is equal to the amount of water it displaces.
- Use the formula:
$$
\text{Volume of object} = \text{Ending Volume} - \text{Starting Volume}
$$
$$
= 75\,\text{mL} - 50\,\text{mL} = 25\,\text{mL}
$$
Final Answer:
$$
\boxed{25} \text{ mL}
$$
This means the volume of the irregular object is
25 mL.
