Describe in step by step detail how you could measure the volume of any irregularly shaped object.

Fill up a graduated cylinder with water. record the measurement. Put the irregularly shaped object in the graduated cylinder. Record what the volume increased to. Subtract the two recorded volumes and the remainder will be the volume of the irregularly shaped item.
