Which tool can be used to determine the volume of a metal bolt?

To determine the volume of a metal bolt, a water displacement method can be used. By submerging the bolt in a graduated cylinder filled with water, the volume of water displaced by the bolt can be measured, which corresponds to the bolt's volume. Alternatively, if the bolt's dimensions are known, its volume can also be calculated using geometric formulas, such as the volume of a cylinder for the main body and a cone for the tip, if applicable.
