Likimääräinen arvo saadaan kaavalla: A ≈ 4 π ( a p b p + a p c p + b p c p 3 ) 1 / p . {\displaystyle A\approx 4\pi \!\left({\frac {a^{p}b^{p}+a^{p}c^{p}+b^{p}c^{p}}{3}}\right)^{1/p}.\,\!} missä arvolla p = 1 , 6075 {\displaystyle p=1,6075} saadaan suhteellinen virhe, joka on korkeintaan 1,061% (Knud Thomsenin kaava); arvo p = 8/5 = 1,6 on optimaalinen lähes pallomaisille ellipsoideille, suhteellinen virhe on tällöin korkeintaan 1,178% (David W. Cantrellin kaava).
S ≈ 4 π a p b p + a p c p + b p c p 3 p . {\displaystyle S\approx 4\pi {\sqrt{\frac {a^{p}b^{p}+a^{p}c^{p}+b^{p}c^{p}}{3}}}.\,\!} Here p ≈ 1.6075 yields a relative error of at most 1.061%; a value of p = 8/5 = 1.6 is optimal for nearly spherical ellipsoids, with a relative error of at most 1.178%.
