God is great desinger

Exodus 38:1-20
Altar of burnt offering, 5 x 5 x 3 cubits height.
The basing for washing
The courtyard: south 100 cubits with 20 poles and 20 bases. East 50 cubits; 3 poles and 3 bases on each side, 15 cubits long curtain on one side of entrance

The curtain for the entrance to the courtyard was made of blue, purple and scarlet yarn and finely twisted linen—the work of an embroiderer. It was twenty cubits long and, like the curtains of the courtyard, five cubits high, with four posts and four bronze bases.
How?
All of the structure of Tabernacle are made with fine measurement and find architecture. How great is the Lord who designed his place on the world.
