A cylindrical bucket is filled completely to the brim with water. Five solid iron steel marbles, each exactly 2 centimeters in diameter, are gently dropped into the bucket. Exactly how much water spills over the sides?
An amount of water equal to the combined volume of the 5 marbles
According to Archimedes' principle, any object submerged in a liquid displaces a volume of fluid exactly equal to its own volume. Since the bucket was full to the brim, the displaced volume spills out.
