When you look at a graduated cylinder anywhere above eye level with the surface of the liquid, it distorts the view and the number (tick mark) you identify as the volume will not be accurate.
Since the salt becomes part of the water, and doesn't take up space in the water, the water level doesn't change.
The height of the water will rise a level equal to the volume of the rock.

The volume of water may appear bigger due to meniscus formation, which is the slight curvature at the surface of the water in the apparatus. This can lead to an apparent increase in volume compared to the marked volume on the apparatus.
Water displacement can accurately find the volume of substances as it represents the same amount of space or volume. An object placed into the water will displace the same amount of water volume as its own volume.

When measuring volumes you should always measure from the bottom of the meniscus - the surface of a volume of liquid always has a slight curve called the 'meniscus'. Since the surface of any still volume of water is not flat (it is always either a convex or concave curve), it should be measured on a level surface at eye level - bend your knees until your eyes are level with the miniscus to measure accurately.
you need to fill a bath half full. then get into the bath and go under the water. the resultant height change in the water level will reflect you volume. I would suggest that you remain under the water for at least 10mins to allow the water surface level to stablise
Water in a glass graduated cylinder adheres to the sides of the cylinder, forming a meniscus which is an upward curve. When reading volume in a cylinder, look at the meniscus at eye level. Read the volume at the bottom of the curve.

Surface tension is in equilibrium. The shape of a sphere has the highest volume to surface area to radius ratio. This shape is the lowest energy level a volume of liquid can have. Deforming it into another shape would involve an increase in surface area and an increase in the average radius.
A cylinder filled with water has properties such as volume, surface area, and weight. The volume of water in the cylinder is determined by its height and radius. The surface area of the cylinder is the total area of its curved surface and two circular bases. The weight of the water in the cylinder is influenced by its volume and density.
Volume
If the object is small enough to place into a graduated container, note the level of the water and then totally immerse the object (being careful that no air bubbles remain under it) by pushing it just below the surface. Note the difference in the water level, and calculate the volume by multiplying the difference in water level times the area of the graduated container.
The upper surface of water is called the water's surface or water level. It is the boundary where the water meets the air above it.
Since the salt becomes part of the water, and doesn't take up space in the water, the water level doesn't change.
To find the volume of an irregular solid, you can use a graduated cylinder and the water displacement method. First, fill the graduated cylinder with a known volume of water and record this level. Then, gently submerge the irregular solid in the water; the rise in water level indicates the volume of the solid, which can be determined by subtracting the initial water level from the new water level. This method effectively measures the volume of the solid without needing its dimensions.
