To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
This is because they need to fit in anything!
It doesn't necessarily. The parameters of the experiment need to be more thoroughly defined.
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.
Enzymes need water for two reasons. One, they are like a miniature body. They need water to live. Water is basically one of their energy sources. Two, enzymes help break down food that you eat. What better to do that than water? You chew it up into small pieces, water breaks it down even further, and then your stomach acid turns what it needs into energy and other stuff, and what it doesn't need into waste.

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.
A surface is where things happen between what is on one side of the surface and the other. Thus in general if you want more of these happenings (eg gas exchange) you need the biggest possible surface area. If however you want to minimise these happenings (eg heat loss) you try and reduce the surface area.
They need a large area because they get in groups and usually have large familys or large packs.
Because, Living things need surface area to survive
The relationship is usually expressed as a ratio: surface area divided by volume. Small cells have a large surface area to volume ratio, whilst large cells have a much smaller value. This is important because the cell absorbs the things it needs, and gets rid of what it doesn't need, through the surface. If the cell gets too large, not enough exchange can take place to keep the cell going, so there is a natural limit on the size to which a cell can grow.
