Explain how to determine the volume of an irregularly shaped object, such as a rock.

Asked by LoanManuel

Answer (2)

If you have no way to accurately measure all of the object's bumps and dimples, then the only way to measure its volume is by means of fluid displacement.
-- Put some water into a graduated (marked) container, read the amount of water, drop the object into the container, and read the new volume in the container. The volume of the object is the difference between the two readings.
-- Alternatively, stand an unmarked container in a large pan, and fill it to the brim. Slowly slowly lower the object into the unmarked container, while the pan catches the water that overflows from it. When the object is completely down in the container, carefully remove the container from the pan, and measure the volume of the water in the pan. It's equal to the volume of the object.

To determine the volume of an irregularly shaped object like a rock, you can use fluid displacement by measuring the water level before and after placing the object in the water. Subtract the initial water volume from the new volume to find the volume of the object. Alternatively, you can use a pan to catch any overflowing water from an unmarked container to find the volume as well.
