Since we have a 14 gallon tank this means that in total we need:
[tex]14\cdot231=3234[/tex]cubic inches.
Now, we know that one inche is equal to 2.54 cm then we have that:
[tex]3234in^3\cdot\frac{2.54\text{ cm}}{1\text{ in}}\cdot\frac{2.54\text{ cm}}{1\text{ in}}\cdot\frac{2.54\text{ cm}}{1\text{ in}}=54995.76cm^3[/tex]finally, and since a liter is equal to 1000 cubic centimeters we have that:
[tex]54995.76cm^3\cdot\frac{1\text{ L}}{1000cm^3}=54.99576[/tex]Therefore we need 54.99576 liters of gasoline (this is approximately 55 liters)
