What is the weight of the fuel in pounds when using 30 gallons if fuel is 6 lb per gallon?

To determine the total weight of the fuel, you can use the formula that involves multiplying the number of gallons of fuel by the weight of each gallon. In this case, the fuel is specified to weigh 6 pounds per gallon.

To find the weight:

1. Start with the number of gallons: 30 gallons.

2. Multiply the number of gallons by the weight per gallon:

30 gallons x 6 pounds per gallon = 180 pounds.

Thus, the total weight of the fuel when using 30 gallons at 6 pounds per gallon is 180 pounds. This calculation is straightforward and is based on basic multiplication, making it essential to know the conversion factor of pounds per gallon when assessing fuel weight for flight operations.
