Table 2 shows the height and mass of two adults.
| Person | Height / cm | Mass / kg |
|---|---|---|
| X | 180 | 80.80 |
| Y | 162 | 50.50 |
The surface area of a person is estimated using the following formula:
Surface area in m2=height in cm×mass in kg3600 \text{Surface area in m}^2 = \sqrt{\frac{\text{height in cm} \times \text{mass in kg}}{3600}} Surface area in m2=3600height in cm×mass in kgThe volume of a person is estimated using the following formula:
Volume in m3=mass in kg1010 \text{Volume in m}^3 = \frac{\text{mass in kg}}{1010} Volume in m3=1010mass in kgUsing suitable calculations, deduce which person has the smaller surface area to volume ratio.
