To find the volume of an irregular shaped object, you'll need to use a method called water displacement. Here's the equipment you'll need:

* A graduated cylinder or beaker: This is a container with markings that allow you to measure the volume of liquids.

* Water: This is the liquid you'll use to displace.

* The irregular shaped object: This is the object whose volume you want to find.

Here's how the method works:

1. Fill the graduated cylinder or beaker with a known volume of water. Record the initial water level.

2. Carefully submerge the irregular shaped object in the water. Make sure the object is fully submerged and no air bubbles are trapped.

3. Observe the new water level. The difference between the initial water level and the final water level is equal to the volume of the object.

Example:

If you start with 50 ml of water in the graduated cylinder and the water level rises to 75 ml after you submerge the object, then the volume of the object is 25 ml (75 ml - 50 ml = 25 ml).

Important Note: This method works best for objects that don't absorb water. For objects that do absorb water, you might need to use a different method, like displacement with a non-absorbing liquid or a volume displacement device.
