Determine the volume of irregular-shaped objects:
A student performs an experiment to find the volume of an irregular metal piece using the water displacement method.
A iron key is placed in a measuring cylinder containing 33 \(mL\) of water. After placing the stone, the water level rises to 59 \(mL\).
Calculate the volume of iron key.
Volume =
∴ Volume of iron key = \(cm^3\)
