How many pieces of 6ft x 6ft lap fencing will i need including posts?

I need to fence off part of my garden which measures 30ft 8 inches. I want to use 6ft x 6ft lap fencing panels and 3inch posts (one at either end) so how many fence panels will i need and how many posts all together?|||You will need 6 posts and 5 sections of fence. This may leave 8%26quot; at the end depending on how the fence connects to the posts (inside fit or outside).
