whats the tallest mountain in the world if you included the ones that are completely sobmerged?

"Mountains are generally measured from sea level, in which case Mount Everest (29,028 feet; 8,848 meters) is king." 8,848 m

(Everest)

"Hawaii's Mauna Kea, though, rises an astonishing 33,476 feet (10,203 meters) from the depths of the Pacific Ocean floor. Measuring from base to peak, Mauna Kea is the tallest mountain on earth." 10,203 m

(Mauna Kea)

"A third way to determine the world's highest mountain is to measure the distance from the center of the earth to the peak. Using this method, Chimborazo in the Andes triumphs. Although it stands but 20,561 feet (6,267 meters) above sea level, its peak is the farthest from the earth's center." 6,267 m

(Chimborazo)

I don't know about sobmerged but submerged, there are mountains taller than anything on dry land.

On dry land, Mt Everest is NOT the highest mountain.
