When reading the volume of a liquid in a graduated cylinder, which part of the water's curve should be observed?

• The highest point of the water level.

• The lowest point of the meniscus.

• Any point along the curved surface.

• The point where the water touches the cylinder's edge.

Which method is most suitable for determining the volume of an irregularly shaped object, such as a stone or a marble?

• Calculating length × width × height.

• Using the water displacement method.

• Weighing the object on a scale.

• Estimating the volume by visual inspection.

A graduated cylinder initially contains 15 mL of water. After an object is submerged, the water level rises to 16 mL. What is the volume of the submerged object?

• 1 mL

• 15 mL

• 16 mL

• 31 mL
