Here are the steps to follow:

1. Fill a graduated cylinder with a known volume of water and record the initial water level.

2. Carefully place the irregular object into the graduated cylinder, ensuring that it is completely submerged and no air bubbles are trapped.

3. Observe and record the new water level.

4. Subtract the initial water level from the final water level to determine the volume of water that the irregular object displaced.

5. Calculate the mass of the irregular object.

6. Then divide the mass by the volume of the displaced water to obtain the density of the object in grams per cubic centimeter (g/cm³).

Formula:

Density (ρ) = Mass (m) / Volume of Displaced Water (V)

Where:

- Density (ρ) is in g/cm³

- Mass (m) is in grams (g)

- Volume of Displaced Water (V) is in cubic centimeters (cm³)

Make sure to perform the experiment accurately to obtain reliable results.
