A student wishes to measure accurately the volume of approximately 40 cm' of water. She has two measuring cylinders, a larger one that can hold 100 cm", and a smaller one that can hold
50 cm". The water forms a meniscus where it touches the glass.

Which cylinder should the student use and which water level should she use to ensure an
accurate result?
