Here is your goal :
Utilize the mathematical method and displacement method to determine volume

Procedure:

1. Measure the length, width and height. Record these figures in the writing space provided in this assignment.

2. Determine the volume of this solid by multiplying these three figures together. Record this result.

3. Determine the volume one of the small rocks by partially filling the graduated cylinder with water. Record this volume. To measure the amount of water, be sure to use the line that comes to the bottom of the meniscus, as shown in the following illustration. Notice the curved blue line. This is called the meniscus. Make your measurements to the bottom of this line.


4. Carefully put the selected rock into the graduated cylinder, taking care not to splash out any of the water. Record this volume in the writing space provided in this assignment.

5. Calculate the volume of the rock by subtracting the volume of the water alone from the volume of the water and the rock. Record the result. Repeat steps 3 through 5 for all the rocks you have selected.
