If a gallon of gasoline weighs 7 lbs, what would be the weight of a 350-gallon tank full of gasoline?

To determine the weight of a 350-gallon tank full of gasoline, you need to multiply the weight of one gallon of gasoline by the total number of gallons in the tank. Given that one gallon of gasoline weighs 7 pounds, you can perform the calculation as follows:

1. Calculate the total weight by multiplying the weight of one gallon (7 lbs) by the number of gallons (350): [ 7 , \text{lbs/gallon} \times 350 , \text{gallons} = 2,450 , \text{lbs} ]

This shows that when you fill a 350-gallon tank with gasoline, the total weight of the gasoline is 2,450 pounds. This computation aligns with the units and the principles of weight calculations for liquids, confirming that the process is accurate and the reasoning is sound.
