How Can I work out the rough surface area of an egg with one of the most simple formulas you know which is still accurate? Please reply soon. Thankyou very much


You can assume the egg to be spherical with a radius R. Area is then 4 x pi x R^2. If you take R to be the longest (shortest) radius of the egg, the surface area is over(under)estimated. You can use the average of the two, however, for a better approximation. I think it is best to use the geometric average R=Squarerootof(R1 x R2) (where R1 and R2 are the major and minor axes) instead of the arithmetic average (R=(R1+R2)/2). You can alternatively assume an ellipsoidal shape, but I do not remember the equation for its surface area.

the surface area is 4pi x major axis x minor axis.
