Exodus 26:7-9

7“Make curtains of goat hair for the tent over the tabernacle—eleven altogether. 8All eleven curtains are to be the same size—thirty cubits long and four cubits wide. That is, about 45 feet long and 6 feet wide or about 13.5 meters long and 1.8 meters wide 9Join five of the curtains together into one set and the other six into another set. Fold the sixth curtain double at the front of the tent.
