We all knew that Mt Everest is world's highest mountain then what it' height?

Well, I found this from an article of the 25 highest mountains in the world:
"Mount Everest or Qomolangma is the Earth’s highest mountain, with a peak at 8,848 metres (29,029 ft) above sea level. It is located in the Mahalangur section of the Himalayas. The international border between China and Nepal runs across the precise summit point."

Don't you know it's rude to ask a mountains weight?

Scoreboard
