A net with a height of 5 meters and a mesh of 7.5 cm, how many threads should be used to spread it?

Recommend the knitting method of "Old Three Gods", 2. 5cm woven board, 1#+ 1. On the 5#+2#pe line, 50cm (depending on the local water depth) of common water will be built after the application, covering 100 c, and three spaces and one space will be tied with a 7 cm lead pendant. Welcome heroes to correct me.

The master of casting net is 12 eyes, 45 pockets, 180 pendant, 7. 8 cm lead pendant, 7 cm waterway pendant, or 8 cm waterway pendant, 7 cm waterway pendant, 2 mm bottom steel rope 55 meters,

This data is not good. 12 per eye and one pocket, 50, 54 pockets are a little too much, and more than 200 pendants are needed, which is difficult to disperse. 12 per eye and one pocket, 59 pockets are a little big.
