Q) Calculate the body surface area of a person with 1.6 m height and 80 kgs weight?

Ans) We can calculate the Body Surface Area(BSA) by following two methods

1) By Mosteller formula

2) By DuBois formula:

#### 1) Mosteller formula:

Height = 1.6 m =160 cm

Weight = 80 kg

=

2) DuBois formula:

**1.88 m**^{2}2) DuBois formula:

BSA (m

^{2}) = 0.007184 X W^{0.425}X H^{0.725}^{ }= 0.007184 X 80

^{0.425}X 160

^{0.725}

^{ }= 0.007184 X 6.43 X 39.6

**= 1.83 m**
