The Alveoli
The surface area of the alveoli is where oxygen and carbon dioxide are exchanged across membranes. A large surface area enables a greater amount of gas transfer. The skin has two main functions: one is holding all our bits in one place and the other is to maintain body temerature. In the latter role, a large surface area is good for cooling the body but bad for keeping warm. So it is a compromise.
Leaves are broad, thin and flat to provide a large surface area, to absorb sunlight for photosynthesis. :)
A cell's volume is the amount of material that can fit into the cell. A cell's surface area is the total amount of material that makes up the outside of the cell. The ratio of surface area to volume is the amount of surface area per unit volume of an object or collection of objects.

to provide a greater surface area in the organelle (increase surface area)
They have a large surface area so there is enough area for heat radiation.
Rugae is the folding of the surface of an organelle to increase the surface area of a volume.
A small amount of ice generally melts faster than a large amount of ice because of the difference in surface-area to volume ratios. Heat transfer with the surroundings occurs only at the boundaries of the ice. The rate of melting is thus directly proportional to the surface area. Additionally, the amount of ice to be melted is dependent on the volume. The more ice, the longer it takes to melt. Thus, a small cube of ice will melt faster because it has a greater surface area to volume ratio than a large block of ice.
Your lungs provide a very large surface area for gas exchange.

One with a large surface area because the solvent will be able to dissolve more solute simultaneously.
