Answer :
Let's begin by identifying key information given to us:
Volume of water = 56 in^3
Time = 2 hours
[tex]\begin{gathered} V=56in^3 \\ t=2hrs \\ \end{gathered}[/tex]To calculate how much volume of water will drip after 7 hours, we use simple proportion as shown below
[tex]\begin{gathered} 56in^3=2hrs \\ x=7hrs \\ \text{Cross multiply, we have:} \\ 2x=7\cdot56 \\ \frac{2x}{2}=\frac{7\cdot56}{2} \\ x=196in^3 \end{gathered}[/tex]At 7 hours, the amount of water to have dripped will be 196 cubic inches.
Hence, option B is the correct answer
