Question

Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

A.

1.55 m2

B.

1.83 m2

C.

0.47 m2

D.

0.45 m2

Answer 1

B.
`1.83\text{ m}^2`

Explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

`\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}* \text{Weight (kg)}}{3600}}`

Substitute the values:

`\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}* 80\text{(kg)}}{3600}}`

`\text{Body surface area}( m^2)=\sqrt{(12,000)/(3600)}`

`\text{Body surface area}( m^2)=√(3.3333333)`

`\text{Body surface area}( m^2)=1.825741`

`\text{Body surface area}( m^2)=1.83`

Therefore, the body surface area of the person would be 1.83 square meters.
