If an aircraft's fuel tank contains 300 gallons and the total volume is to be calculated in cubic feet, what is the volume when 7.5 gallons equals 1 cubic foot?

To determine the volume of the fuel tank in cubic feet, it's essential to convert the gallons into cubic feet using the provided conversion factor of 7.5 gallons per cubic foot.

Given that there are 300 gallons in the tank, you would perform the calculation by dividing the total number of gallons by the conversion factor:

[

\text{Cubic Feet} = \frac{\text{Gallons}}{\text{Gallons per Cubic Foot}} = \frac{300 \text{ gallons}}{7.5 \text{ gallons/cubic foot}}

]

Carrying out this division gives you:

[

\text{Cubic Feet} = \frac{300}{7.5} = 40 \text{ cubic feet}

]

This reveals that the total volume of the fuel tank is indeed 40 cubic feet. Thus, the correct answer accurately reflects this conversion calculation. Understanding how to apply unit conversions is critical in practical aviation maintenance situations, where accurate measurements affect safety and efficiency.
