The highest mountain in the world is Mt. Everest, whose peak is 29,029 feet above sea level. But the tallest mountain is Mauna Kea. The base of Mauna Kea is 19,669 feet below sea level, and its peak is 33,465 feet above its base. How much higher above sea level is Mt. Everest than Mauna Kea?

So we know that Mt. Everest has a peak that is 29,029 feet above sea level.

To find how much Mauna Kea is above sea level then we would subtract the feet below sea level (19,669ft) from the overall height of the mountain (33,465ft). Like this:

33,465ft - 19669ft = 13,796 feet

Now that we know both mountains height above sea level, we can answer the question.

We will take Everest's height above sea level and subtract Mauna's height above sea level. Like this:

29,029ft - 13,796ft = 15,233

Therefore, Mt. Everest is 15,233 feet taller above sea level than Mauna Kea.

Hope this helps!
