How did student , most probably measure the volume of 10 glass marbles?

To measure the volume of 10 glass marbles, a student would most likely use either the displacement method or the water immersion method. Here's how each of these methods work:

1. Displacement Method:
- Step 1: Fill a graduated cylinder or a beaker with a known volume of water, such as 100 milliliters (ml).
- Step 2: Record the initial water level in the graduated cylinder or beaker.
- Step 3: Gently drop the 10 glass marbles into the cylinder or beaker, making sure they are fully submerged.
- Step 4: Measure and record the new water level in the cylinder or beaker. The difference between the initial and final water level represents the volume of the marbles.
- Step 5: Calculate the volume by subtracting the initial water volume from the final water volume. The result will give you the volume of the 10 marbles.

2. Water Immersion Method:
- Step 1: Fill a graduated container, preferably a large measuring cup or beaker, with water.
- Step 2: Record the initial water level in the container.
- Step 3: Slowly submerge one marble into the water and observe the water level rise. Carefully remove the marble from the water and record the new water level.
- Step 4: Repeat step 3 with another marble, but this time, record the change in water level.
- Step 5: Repeat this process, one marble at a time, until you have used all 10 marbles.
- Step 6: Add up the recorded changes in water level. The sum will give you the total volume of all 10 marbles.

By using either the displacement method or the water immersion method, a student can determine the volume of 10 glass marbles accurately.
