Well the width is 0.20 meters. Since there are a hundred centimeters in a meter, we just have to move the decimal point two times to the right to get a 20 centimeter width.
How much is each gallon or how far are you going is the question you should be asking
The formula we can use here is the Plancks equation:
E = h c / ʎ
where h is Plancks constant = 6.626 × 10-34 m2 kg / s, c
is speed of light = 3 x 10^8 m/s and ʎ is wavelength = 656.1 x 10^-9 m
Therefore E is:
E = (6.626 × 10-34 m2 kg / s)
* (3 x 10^8 m/s) / 656.1 x 10^-9 m
<span>E = 3.03 x 10^-19 J</span>

Explanation:
A net ionic equation shows only the chemical species that are involved in a reaction, while a complete ionic equation also includes the spectator ions(Khan Academy).
From the species shown in the image we can write the molecular equation, ionic equation and net ionic equation and also identify the spectator ions.
Chemical equation: KX + BY --------> BX + AY
Ionic Equation; X^- + A^+ + B^+ + Y^- -----> BX + A^+ + Y^-
Spectator ions; A^+ and Y^-
Net Ionic Equation; X^- + B^+ ------> BX
