Calculating the surface area of an ellipsoid does not have a simple exact formula such as a cube or other simpler shape does. It can be calculated with the known measurement of edge length. The formula depends on the type of the solid.
W is the width.
Use our online triangular prism calculator to find the surface area within a blink of eye. Thats the same answer we got before. It is total of the area covered by the surface of the object. The surface area formula for a cone given its diameter or radius and height is p x diameter 2 2 p x diameter 2 x diameter 2 2 height 2 where diameter 2 is the radius of the base d 2 x r so another way to write it is p x radius 2 p x radius x radius 2 height 2 as seen in the figure below.
