Calculating Ellen's Body Surface Area (BSA)

Calculating Ellen's Body Surface Area

Explanation:

To calculate Ellen's Body Surface Area (BSA), we need to first convert all measurements to metric units and then apply the Mosteller formula. Here are the conversions and calculations:

• Weight: 193.6 lb = 87.817 kg (1 lb = 0.453592 kg)
• Height: 6 ft 6 in = 78 in = 198.12 cm (1 in = 2.54 cm)

Next, we apply the Mosteller formula:

BSA (m2) = √[(height (cm) × weight (kg))/3600]

Plugging in Ellen's values, we get:

BSA (m2) = √[(198.12 × 87.817)/3600] ≈ 2.20 m2

Therefore, Ellen's BSA is approximately 2.20 square meters.
