According to http://www.anniebees.com/China/China_29.htm , each silkworm cocoon is made of a single fiber about 3600 feet long, and eight fibers are twisted together to make a usable thread, so 40000 silkworms would make 5000 threads 3600 feet lopng.
At 200 threads per inch (400 inches of thread per square inch), eight cocoons would make (3600 x 12) / 400 = 108 square inches of cloth. Therefore, 40000 silkworms would make (5000 x 108) / 144 = 3750 square feet of cloth. Note that all the silkworms are killed in the process.
