Given here is the geometric formula for the calculation of surface area of an ellipsoid given the axis values. Here in the formula, a, b and c defines the vertical distance from the origin of the ellipsoid to its surface. Surface area of an ellipsoid formula is derived as 4π[((ab)1.6+(ac)1.6+(bc)1.6)/3](1/1.6). It is calculated mainly based on three axis (Axis 1, Axis 2 and Axis 3). Also, you can refer to the below calculator link that shows the calculation of SA of an ellipsoid.
a, b and c defines the vertical distances from the origin of the ellipsoid to its surface.
Surface area of an ellipsoid formula is given above for you to calculate the result, just substitute the axis values in this formula. Also in the above-given calculator link, you will get the resultant value in different measurements such as cm2, m2, and so on.
