Hi guys:

I'm trying to fence my plot of land in Benin city.  I'm doing it by proxy (in-law) since I don't live at home.  I just want you guys to help me out with some information:

1.  What amount of 9 inch blocks will it take to fence a plot 100x100 to a height of 2 metres?

2.  Which is more beneficial, buying blocks or molding your own?

3.  Can you please provide any other useful inform related?  (Some guy was talking about
     using prefab slabs.)

Thanks hommies.[/b]
