Explain how to use the displacement method to find the volume of an irregularly shaped object.

Place the object in the graduated cylinder, and record the resulting water volume as "b." Subtract the volume of the water alone from the volume of the water plus the object. For instance, if "b" was 50 milliliters and "a" was 25 milliliters, the volume of the irregularly shaped object would be 25 milliliters.

Even if your door is closed, you would still smell the odors because of the space under the door and the space that is needed to close the door.
