Vedmedyk [2.9K]

By definition, we have that the conversion of a US gallon to liters is given by:
1 liter = 3.78541 gallons
Therefore, we can apply the following rule of three:
1 liter ---------------------> 3.78541 gallons
5100 liters --------------> x
Clearing x we have:
$x = (5100) * (3.78541)

x = 19305.591$
two significant figures:
$x = 19000
$
Answer:
The lung capacity of the blue whale is:
$x = 19000 gallons$
