25 And they shall be eight boards, and their sockets of silver, sixteen sockets; two sockets under one board, and two sockets under another board.
25 וְהָיוּ֙ שְׁמֹנָ֣ה קְרָשִׁ֔ים וְאַדְנֵיהֶ֣ם כֶּ֔סֶף שִׁשָּׁ֥ה עָשָׂ֖ר אֲדָנִ֑ים שְׁנֵ֣י אֲדָנִ֗ים תַּ֚חַת הַקֶּ֣רֶשׁ הָאֶחָ֔ד וּשְׁנֵ֣י אֲדָנִ֔ים תַּ֖חַת הַקֶּ֥רֶשׁ הָאֶחָֽד׃
As you can see, there were eight (8) boards in the western wall of the Tent: six(6) regular boards (each being 1.5 cubits long and 10 cubits tall), and there were 2 special corner boards made out of two curved regular boards(each being 1 cubit in outside diameter and also 10 cubits tall).
The thickness of all the boards was 0.5-(1.5/pi)=~0.0225 cubits - roughly, a fingerbreadth.
And last but not least, there were sixteen(16) silver sockets - a pair for each of the boards. Twelve(12) regular sockets(just like on the north and south side of the Tent) and 4 special sockets for the corner-boards.
However, each and every board socket weighted exactly one(1) talent of silver(as per Exodus 38:27), even though the corner boards sockets were of a different shape.
