$$ \begin{cases} 1\ut{A.Barrel}&=7056\ut{in^3}\\ 1\ut{C.Barrel}&=5826\ut{in^3}\\ \end{cases} $$ $$ \begin{aligned} \Ans&=73\ut{A.Barrel}-73\ut{C.Barrel}\\ &=73(1\ut{A.Barrel}-1\ut{C.Barrel})\\ &=73(7056\ut{in^3}-5826\ut{in^3})\\ &=73\cdot1230\ut{in^3}\\ &=73\cdot1230\ut{in^3} \cdot \(\frac{2.54\ut{cm}}{\ut{in}}\)^3\cdot\frac{1\ut{L}}{1000\ut{cm^3}}\\ &=\frac{18392430957}{12500000}\ut{L}\\ &=1471.39447656\ut{L}\\ &\approx1.5\times10^3\ut{L} \end{aligned} $$
