So,
All we have to do is multiply all three dimensions together.
First, convert all fractions into improper fractions.
\(3 \frac{1}{5}--\ \textgreater \ \frac{16}{5}\)
\(1 \frac{3}{4} --\ \textgreater \ \frac{7}{4}\)
\(2 \frac{1}{4} --\ \textgreater \ \frac{9}{4}\)
Now multiply the fractions together.
\(\frac{16}{5}*\frac{7}{4}*\frac{9}{4}= \frac{2*2*2*2*3*3*7}{2*2*2*2*5}\)
\(\frac{3*3*7}{5}--\ \textgreater \ \frac{63}{5}\ or\ 12 \frac{3}{5}\ ft.^3\)
The correct option is C.
