Since water displacement is solely dependent on volume, the 1.0 cubic centimeter sample of lead and the 1.0 cubic centimeter sample of glass would displace the exact same amount of water since they have the same volume. The amount of water displaced by each of them would be equal to their volumes, 1.0 cubic centimeters.
Work Step by Step
Water displacement is the amount that water rises when a substance is dropped into it. The amount that the water rises is equal to the volume of the sample. Since the lead and the water had the same volume, we can disregard their identity since volume is the only physical property that matters.
