3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{gal}(\mathrm{US})& =\frac{0.00378541\cancel{m3}}{0.0000295735\cancel{m3}}\times 1\mathrm{floz}(\mathrm{US})\\ & =\frac{0.00378541}{0.0000295735}\mathrm{floz}(\mathrm{US})\\ & =128.000067628\mathrm{floz}(\mathrm{US})\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{floz}(\mathrm{US})& =\frac{0.0000295735\cancel{m3}}{0.00378541\cancel{m3}}\times 1\mathrm{gal}(\mathrm{US})\\ & =\frac{0.0000295735}{0.00378541}\mathrm{gal}(\mathrm{US})\\ & =0.007812495872\mathrm{gal}(\mathrm{US})\end{array}$$
