Why does the brain need to have a larger surface and not a larger volume?

I was reading the Selfish Gene and I got to the part where the autor says that the human brain stores data much more efficiently and has a much more complex retrieval mechanism of memories than a computer counterpart. If storage and access are the goals, wouldn’t a “smooth” brain make more sense?

Only the surface of the brain (oversimplifying but generally correct) has the cell bodies where ‘meat’ of the brain actually is. It does all the processing and thinking. The rest of the brain is just wires that connect the bits of the surface together. Having a really folded brain means that these connections don’t have to be as long.
