So,

All we have to do is multiply all three dimensions together.

First, convert all fractions into improper fractions.

$3 (1)/(5)--\ \textgreater \ (16)/(5)$

$1 (3)/(4) --\ \textgreater \ (7)/(4)$

$2 (1)/(4) --\ \textgreater \ (9)/(4)$

Now multiply the fractions together.

$(16)/(5)*(7)/(4)*(9)/(4)= (2*2*2*2*3*3*7)/(2*2*2*2*5)$

$(3*3*7)/(5)--\ \textgreater \ (63)/(5)\ or\ 12 (3)/(5)\ ft.^3$

The correct option is C.

Three less than x is equal to 13
