1, have you ever eaten Lamian Noodles?

The master's craft is exquisite. The surface he pulled was 1mm square. What is the total length of noodles?

Answer the first one first. I ate. . .

Second, because the volume of Lamian Noodles is 20cm 3, noodle thickness * noodle length = noodle volume = 20cm 3, the thickness is 0.1cm 22, and the length is 20/0. 1=200. It is 200cm, and the answer given is wrong.
