Question

Using a formula estimate the body surface area of a person whose height is 5 feet and who weighs 120 pounds.

A.

1.52 m2

B.

0.32 m2

C.

1.13 m2

D.

55.9 m2

Answer 1

(A) 1.52 m²

Explanation:

As per the given data of the question,

Height of a person = 5 feet

As we know that 1 feet = 30.48 cm

∴ Height = 152.4 cm

Weight of a person = 120 pounds

And we know that 1 pound = 0.453592 kg

∴ Weight = 54.4311 kg

The Mosteller formula to calculate body surface area (BSA):

`BSA(m^(2))=\sqrt{(Height (cm)* Weight(kg))/(3600)}`

Therefore,

`BSA=\sqrt{(Height (cm)* Weight(kg))/(3600)}`

`BSA=\sqrt{(152.4*  54.4311)/(3600)}`

`BSA= 1.517 m^(2) = 1.52 m^(2)`

Hence, the body surface area of a person = 1.52 m²

Therefore, option (A) is the correct option.
