I am doing a very small foyer (4-1/2' X 6-1/3') and I have a full box
+ few scraps left over from my kitchen. I will need at least another 5 planks to complete the floor with this style. I figure a box should well cover it, but would buy what you
have. I would try the other style but the locking system seems to be different on newer styles.
I am in Vancouver Washington (By Portland Oregon).
Thanks
