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 density of the lead in kg `m^(-3)`

Explanation

To find the density of the lead piece, we will follow these steps:

### Step 1: Determine the mass of the lead piece
The mass of the lead piece is given as 115 grams.

### Step 2: Calculate the volume of the lead piece
The volume can be found by measuring the change in water level in the measuring cylinder.
