Answer:
10,203 meters tall
Step-by-step explanation:
Sea Level is given a value of 0 and is measured as the starting point. Anything below sea level would be a negative value. Therefore, to calculate the total height of Mount Mauna Kea we would need to add the height below sea level with the height above sea level as both positive values.
5854m + 4349m = 10,203m
Finally, we can see that Mount Mauna Kea is 10,203 meters tall.
