The answer process is as follows:
(1) 1 serving =6 cm;
(2) 10000 copies =6* 10000=60000 cm =600 m.
(3) 100000 copies =6* 100000=600000 cm = 6000m.

China unit
The traditional units of length in China are Li, Zhang, Chi, Inch, Xun, Jie, Fu, Zhi, Yi, Bu, Chang, Ya, Yan, Ji, Rail, Luo, Millimeter, Li and Min. The basic transformation relationship is as follows:
1 ft = 10 ft; 1 ft = 10 inch; 1 inch = 10 points; 1 = 10%.
1 sheet ≈ 3.33m; 1 ft ≈3.33 decimeter; 1 inch ≈3.33 cm.
1km = 1000m； 1 meter (m) = 100 cm; 1 cm =10mm.
1 Li = 150 sheets = 500m; 2 Li = 1 km (1000 m).
