Surface area to volume ratio

Medium

Table 1 shows features of two mammals.

Flying squirrels are gliding mammals; ground squirrels are ground-living mammals.

Table 1

Mammal	Mean body mass / $kg\text{kg}$	Mean lung volume / $cm3\text{cm}^3$
Flying squirrel	$0.15$	$9.45$
Ground squirrel	$0.25$	$4.50$

Calculate how many times the lung volume per unit of body mass of the flying squirrel is greater than that of the ground squirrel.

Give your answer to an appropriate number of significant figures.

Give one suggestion to explain this difference.
