Hello,
In this case, for the given reactants we identify the following chemical reaction:
Thus, we evidence a 1:1 molar ratio between KOH and HCl, therefore, for the complete neutralization we have equal number of moles, that in terms of molarities and volumes become:
Hence, we compute the volume of HCl as shown below:

Answer:
The volume of the gasoline in the tank is 18.85 cubic feet
Explanation:
The tank is a cylinder. The equation for calculating the cylinder volumen is πr²*h, r is radius and h is height. π is approximately 3.1416. So, The tank is resting horizontally on its side, its radius is 2 feet/2= 1 feet. h=a tank long= 6 feet.
With equation:
Vol gasoline=3.1416*1²*6=18.85 feet ³
