Table 2 shows the nose-to-tail length and mass of two juvenile harbor seals.
| Harbor Seal | Length / cm | Mass / kg |
|---|---|---|
| A | 160 | 90.00 |
| B | 125 | 45.00 |
The surface area of a harbor seal is estimated using the following formula:
Surface area in m2=length in cm×mass in kg4000 \text{Surface area in m}^2 = \sqrt{\frac{\text{length in cm} \times \text{mass in kg}}{4000}} Surface area in m2=4000length in cm×mass in kgThe volume of a harbor seal is estimated using the following formula:
Volume in m3=mass in kg1000 \text{Volume in m}^3 = \frac{\text{mass in kg}}{1000} Volume in m3=1000mass in kgUsing suitable calculations, deduce which seal has the smaller surface area to volume ratio.
