Answer:
a) 2891.012 
b) 0.496 
Step-by-step explanation:
We know 1 US gallon = 3.79 L
Also
1L =61.024 
and given 1 cubit - 18 in
a) gas tank = 12.5 Us gal. = 12.5×3.79 = 47.375L=47.375×61.024= 2891.012 
b) as 1 cubit =18 inches
or
18 inches = 1 cubit
==> 1 inch = 1/18 cubit =0. 055555556 cubit
Taking cube on both sides;
==>
×0.055555556×0.055555556=0.000171468 
so size of gas tank = 2891.012×0.000171468=0.495715375=0.496
