Answer:

65.824 gallons

Step-by-step explanation:

First, we determine the volume of water in the bathtub in cubic feet.


\begin{gathered} \text{Volume}=5.0*2.2*0.8 \\ =8.8ft^3 \end{gathered}

Given:


1ft^3\text{ of water=}7.48\; gallons.

Thus, we have that:


\begin{gathered} 8.8\; ft^3\text{ of water=}7.48*8.8 \\ =65.824\text{ gallons} \end{gathered}

65.824 gallons of water were used to fill the tub.
