A container of water has its smallest volume at?

A container of water has its smallest volume at its lowest point when it is in a completely filled state. If the container is partially filled, the volume will depend on the shape and dimensions of the container. For example, a narrow container may hold less water than a wider one, even if both are filled to the same height. Ultimately, the smallest volume occurs when the container is emptied or when any irregularities or shapes are taken into account.
