Qantas Frequent Flyer - A380 Seat

Has anyone any idea how many Y seats would fit into a F A380 space, i know on a BA747 6.5 Y seats fit into the F space, would be interesting to know re A380, any mathematics around:)

You could compare Qantas & Emirates seat maps as they have Economy in the same space.
