Answer 2

In 1856, Everest's height was first calculated to be 8,840 meters (29,002 feet) above sea level by a team led by British surveyor Sir George Everest, the man whom the mountain was named after. Later, in 1955, the figure was adjusted by eight meters to 8,848 (29,028 feet), which has remained the official height to date.

Indian mathematician and surveyor Radhanath Sikdar was probably the first person to identify that Mount Everest (then known as peak XV) was the world's highest peak as he was the first person to calculate the height of the mountain in 1852.
