The image you uploaded contains a problem that involves calculating the surface area of the human body using a specific formula related to height and weight.

From what I can see in the image, the problem gives the height of a 5-year-old boy as **115 cm** and his weight as **21 kg**. There seems to be a reference to a formula to calculate the body surface area (BSA), but it is not fully visible in the image.

Typically, one common formula for calculating BSA is the **Mosteller formula**, which is expressed as:

\[
\text{BSA} = \sqrt{\frac{\text{height (cm)} \times \text{weight (kg)}}{3600}}
\]

Now, applying this formula:

Given:
- Height = 115 cm
- Weight = 21 kg

Let's calculate the BSA.

I'll calculate this now.The body surface area (BSA) of the 5-year-old boy, based on the given height of 115 cm and weight of 21 kg, is approximately **0.819 m²**.

Here are 5 related questions you might find useful:
1. How does body surface area change with age?
2. Why is BSA important in medical dosing?
3. What other formulas can be used to estimate BSA?
4. How does weight affect BSA compared to height?
5. Can BSA be used to assess health conditions?

**Tip:** The Mosteller formula is popular for BSA calculations because it's easy to use and provides results close to more complex methods.

The surface area in square meters of the human body can be found using the Mosteller formula:

\[
\text{BSA} = \sqrt{\frac{\text{height (cm)} \times \text{weight (kg)}}{3600}}
\]
Find the surface area of a 5-year-old boy with a height of 115 centimeters and a mass of 21 kilograms.

Learn how to calculate the Body Surface Area (BSA) of a 5-year-old boy using the Mosteller formula. The problem involves using the height (115 cm) and weight (21 kg) of the child to determine the surface area in square meters.
