Surface area is the perimeter (amount of space around a shape) around a shape.
For example:
I have a rectangle
So:
3+3=6
9+9=18
18+18=36cm2

Give an example of a situation where a large surface area is used to reduce pressure?
Quicksand
How do you work out the outer surface area of a cube?
The answer depends on what information you have about the cube. If, for example, you know the volume, V, then the surface area is 6*cuberoot(V)^2. If you have the lengths of an edge, s, then it is 6*s^2.
What is an example of a raised flat area?
a surface that does not move
How does surface area work?
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?
In what way is the surface area more important for cells than volume?
For example, the amount of nutrients a cell can absorb are proportional to its surface area.

How can the surface area of a polyhedron be found?
Find the surface area of each face then add them together to give the total surface area.
What is a real world example of surface area?
A practical need to calculate surface area arises, for example, when you need to paint your house. The amount of paint you need is proportional to the surface area you want to paint.
What can change the surface area to volume ratio?
Yes. There are ways to do that, but it depends on what you wish to change the surface area of. Changing the surface area of something like, say, a shotput is difficult, but changing the surface area of a balloon can be accomplished by merely blowing it up (more) or deflating it.

Why is it important that the gills of a crayfish give them a large surface area?
It is important that the gills of a crayfish give them a large surface area because it helps the crayfish to breathe. The bigger the surface area, the more oxygen in the crayfishes system.Ê

If area is measured in square units and volume in cubic units how is Surface area measured?
The answer is in the first part of your question. By this I mean that surface area would be measured in square units. For example, the surface area of the rectangle was 32cm squared.
What is the relationship between surface area and rate of evaporation?
Evaporation is a process that takes place at the surface of a liquid, therefore the rate of evaporation is directly related to the surface area. Twice as much surface area will give you twice as much evaporation.
How deep a sub surface void will show up in magnetic particle inspection?
