The reason we consider the surface area of the entire mass of Mercury, including the part of the surface that is in contact with the glass, is because mercury does not adhere at all to glass. So the surface tension of the mercury acts over its entire surface area, including where it is in contact with the glass. If instead of glass, the tube were made out of copper, the situation would be very different. Mercury aggressively adheres to copper. So in a copper tube, the level of mercury at the center of the tube will be lower rather than higher than at the edges

A parallelogram need not be a square, it need not be a rhombus but it is a convex shape.
What is the shape of your eyelid?
convex
What is a convex heptagon?
No. Convex simply means that if you have a straight line segment joining any two points in (or on) a convex shape, then every point on that line segment in inside or on the shape. A convex shape can have 2 or more dimensions, it can by a polygon or have curved sides.
What shape has all diagonals inside?
A convex shape.
How can you find a generalization for a triangle a parallelogram and a convex shape?
A parallelogram cannot be generalised to a convex shape with an odd number of sides.
What are some examples of convex shapes?
Most all corrective lenses are convex. Anything round, or even just "roundish" has a convex shape. From bowling balls to chickens' eggs, they are all convex, or "rounded outward" in shape.
Is a heart a convex or concave shape?
Convex. The hearts inward point makes this so.
Why does mercury have convex meniscus?
Mercury has a convex meniscus because the intermolecular forces between mercury atoms are stronger than those between mercury atoms and glass molecules of a tube. The outermost mercury atoms are attracted to central mercury atoms and go towards the center of the tube. This force of attraction is slightly stronger than the force of gravity on the uppermost mercury molecules, so the meniscus is slightly elevated to a peak and is convex.
What lens is a converging lens double-convex spherical-convex plano-concave or convexo-concave lens?
A converging lens is also known as a magnifying lens. The shape of the lens is a double convex shape.
What shape are the lens inside your eyes?
convex
