Exodus 26:16

Ten cubits shall be the length of a board
Or five yards, according to the common cubit:

and a cubit and a half shall be the breadth of one board;
or three quarters of a yard; and from hence we may learn what were the height and the length of the tabernacle; according to the common computation of a cubit, it was but five yards high and fifteen long, since there were but twenty boards on each side, ( Exodus 26:18 Exodus 26:20 ) , but if three inches are added to each cubit, it will make its measures considerably larger: Josephus ^F17 says the boards were four fingers thick: according to Bishop Cumberland the boards of the tabernacle, containing fifteen Jewish square cubits, were very near fifty English square feet in their length and breadth.
