Interesting figures:
Container 20ft (6m length):
-if loaded on trailer 10m length: 11+11+2.7mil.= 25 million containers x 10 m = a train of 250,000,000 m = 250,000 km
(isn't it delightful - and easy - to count with the metric units? how much it would be in ft and miles?)
That's 6 times around the globe every year (provided that Earth is not flat)
i.e.: 70,000 containers loaded down every day...
