How would you measure the volume of an irregular solid? Explain ALL the steps
1. Fill up a graduated cylinder with water, measure the volume of water, and write it down. 2. Throw the irregular solid in the graduated cylinder 3. Measure the new volume of water in the graduated cylinder 4. Subtract the volume BEFORE and AFTER throwing the irregular solid.
