Explanation: From, the index (depth-range) provided below the image, we can conclude that the sea level is low abnormally at the region A as it has the maximum depth below the mean sea level in the diagram i.e -30 cm.
It is clearly represented in the index that-
Region A shows a depth of about -30 cm height below the mean sea level
Region B shows a depth of about 30-40 cm above the mean sea level
Region C shows a depth of about 5-15 cm above the mean sea level
Region D shows a depth of about -10 to -20 cm below the mean sea level.
The length would be 2, the width would be 2, and the height would be 2. The formula for volume is length x width x height. So, you would multiply 2 x 2 x 2. The answer would be 8 micrometers cubed.
