Because to get in and out you have to cross the cell's surface and if it has a bigger area more can happen than with a smaller area. To increase the surface area volume ratio, the cell can reduce in size or change its shape.
The wind is an agent of erosion. The vegetation growing in an area affects the ability of the wind to modify the surface of the Earth by holding the soil in place, thus preventing erosion.

The surface area can be increased so that it can absorb more materials. The microvilli protrude from the epithelial cells lining.
increased surface area, increases output
It would help if the question was less obscure. What do you mean by "work"? How the surface area affects chemical processes (for example the surface area of catalysts), or diffusion, or surface areas and friction?
colour, shape, surface area
air resistance affects
Surface area affects collision rate because the larger the surface area the more air resistance is acting on it, therefor a larger surface area can slow down collision rate.
Surface area affects several things, such as how quickly an object cools down; the rate of chemical reactions will also depend on the exposed area.
The shape affects the ratio of surface area to volume. The greater the surface are to volume ratio, the faster the magma will cool.
Increasing the Surface Area increases the heat loss. You will find a nice example in the related question link below.
Surface size directly affects the possibility for gas exchange. Volume affects how much the cell can contain. If a cell has a large volume and a small surface area, it will be able to keep in water easily. But if it needs outside gas input for its reactions, the small surface area may be a limiting factor.
