$\text{4.72 gal"~~"17900 mL}$ rounded to three significant figures

#### Explanation:

Start with the relationships between milliliters (mL), quarts (qt), and gallons (gal).

$\text{946 mL = 1 qt}$
$\text{1 gal = 4 qt}$

In order to convert gallons to milliliters, multiply the given number of gallons by $\left(4 \text{qt")/(1"gal}\right)$, then multiply by $\left(\text{946 mL")/(1"qt}\right)$.

$4.72 \cancel{\text{gal"xx(4cancel"qt")/(1cancel"gal")xx(946"mL")/(1cancel"qt")~~"17900 mL}}$ rounded to three significant figures
