A diver dives to a depth of –25.6 feet below sea level. How many feet must the diver rise to reach sea level?

well if you dive 25.6 feet below sea level and then you come back up 25.6 feet wouldn't you be at 0 feet (or sea level) ?

To find out how many feet the diver must rise to reach sea level, we need to calculate the absolute value of the negative depth. The absolute value of a number is the value without its negative sign. In this case, the absolute value of -25.6 is 25.6.

Therefore, the diver must rise 25.6 feet to reach sea level.
