$32$ gallons is how many pints?

Hint: The two units in the above question, which are the gallons and the pints, are both the units of volume. For converting the given number of gallons to the pints, we have to find out equivalent pints in one gallon. For this, we have to find out the number of pints in a gallon. One gallon is equivalent to exactly eight pints. By using the unitary method, for converting the volume in galloons into pints, we need to multiply it by eight so that we can write the conversion equation $\text{pt}=8\times \text{gal}$. On substituting the given number of gallons, which is equal to $32$ gallons, into the conversion equation $\text{pt}=8\times \text{gal}$, we will get the required volume in pints.

Complete step-by-step answer:
We know that the volume of one gallons equivalent to the volume of eight pints. Therefore we can write
$\Rightarrow 1\text{gal}=8\text{pt}$
Using the unitary method, we can say that for converting the volume given in gallons to pints, we need to multiply it by eight. From this information, we can write the below conversion equation from gallon to pints.
$\Rightarrow \text{pt}=8\times \text{gal}$
According to the above question, we are given a volume of $32$ gallons. Therefore, we substitute $32$ gallons in the above conversion equation to get the equivalent volume in pints as
$\begin{align}
  & \Rightarrow \text{pt}=8\times \text{32} \\
 & \Rightarrow \text{pt}=256 \\
\end{align}$
From the above, the equivalent volume in pints is equal to $256$ pints.
Hence, there are $256$ pints in $32$ gallons.

Note: Gallon and pints both are the units of volume, which are unfamiliar among students. Do not try to convert them to the familiar units of milliliters or liters since the conversions are approximate and not exact. The conversion equation $\text{pt}=8\times \text{gal}$ must be remembered as it is.
