📋 Calculation Details

1DuBois: 0.007184 × 70.0^0.425 × 170.0^0.725 = 1.810 m²
2Mosteller: √((170.0 × 70.0) / 3600) = 1.818 m²
3Haycock: 0.024265 × 70.0^0.5378 × 170.0^0.3964 = 1.826 m²
4Gehan & George: 0.0235 × 70.0^0.51456 × 170.0^0.42246 = 1.831 m²
5Boyd: 0.0003207 × 170.0^0.3 × 70.0^(0.7285 - 0.0188×log10(70.0)) = 0.029 m²
