How many pieces for 4'X8' XPS would I need for 27' AGP?

Hi All,

First, great site and thanks to the community here as it has helped me figure out how to prepare for self install AGP. What I cant seem to find (and not sure of the math), is how many boards did you need to create the base of pool? I really do not have a way to get a 4x8 board on own so will have to order and have it delivered. I do not want to under order and be stuck during install. For those who have done it, how many did you use and what did the layout look like?

Thanks a bunch!

ive never done it, but pretty sure you need 20.

I get that you need 21 to be safe, though you can probably get by with 20 by using the trimmings to fill in the spaces.
