# 200 cm3 of water was poured into a beaker. When a piece of iron was dropped into it, the water in the beaker

200 cm3 of water was poured into a beaker. When a piece of iron was dropped into it, the water in the beaker rose to the division indicated by the number 250. Determine the volume of iron.

Given:

V1 = 200 cubic centimeters – the volume of water in the beaker;

V2 = 250 cubic centimeters – the volume of water in the beaker after a piece of iron has been lowered into it.

It is required to determine V (cubic centimeter) – the volume of a piece of iron.

According to Archimedes’ law, a body immersed in a liquid displaces a volume of liquid equal to the volume of the body. Then:

V = V2 – V1 = 250 – 200 = 50 cubic centimeters.

Answer: The volume of a piece of iron is 50 cubic centimeters (0.00005 m3).
