The mass of a lead piece is 115 g. When it is immersed into a measuring cylinder, the water level rises from 20 mL mark to 30 mL mark. Find the volume of the lead piece

Explanation

To find the volume of the lead piece, we can follow these steps:

### Step 1: Identify the initial and final water levels
- The initial water level in the measuring cylinder is at the 20 mL mark.
- The final water level after immersing the lead piece is at the 30 mL mark.

### Step 2: Calculate the change in water level
- To find the volume of the lead piece, we need to calculate the difference between the final and initial water levels.
