The surface area of a knee root of a mangrove tree can be difficult to calculate, as the shape is often irregular and complex as shown by your photograph. To calculate the surface area, you would need to create a 3D model of the knee root and then use computer software or mathematical formulas to determine the surface area.
Alternatively, you could use an indirect method to estimate the surface area. One such method would be to measure the diameter and height of the knee root and use this information to estimate its volume, then divide the volume by the average thickness of the knee root to estimate the surface area.
Hope this could help.
Thank you very much. In the second method as suggested by you, I have few queries. First of all, I assume the shape is a paraboloid ( if i remove the two conical extensions, please note that one cone is slightly broken). How to take the average diameter? Are you suggesting to calculate the volume without conical structure?
Gobardhan Sahoo What's with the average diameter? All you have to do is to get the diameter. To get the diameter of irregularly-shaped objects such as your mangrove knee root, you need to find two points that are the furthest apart from each other within the shape. The distance between these two points is the diameter. Hope this will help you.
I did not get you. Can you please check the attached photograph again? Since the diameter of the paraboloid is variable along the length, I can find out the average diameter from several measurements (shown in horizontal lines). Am I correct? I am excluding the cones (shown in Tick mark) while calculating the average diameter.
