What is the approximate distance from the bottom of the Marianas Trench to the top of Mount Everest?

65,035 feet

The Mariana Trench is the deepest point on the Earth's surface. If you scan the literature, you will find various numbers for the depth of the Mariana Trench. It boils down to: about 36,000 feet below sea level; which is about 6.8 miles down; and that equals about 11,000 meters; or 11 km. That makes the Mariana Trench quite a few feet deeper than Mount Everest is high. If you scan the literature, you will also find several numbers for how high Mount Everest is. NASA currently gives it as 29,035 ft. or 8850 meters. Therefore: 36,000 + 29,035 = 65,035 feet Your choice af asking 'approximately' is supported by the following site the source of the above information.
