$\displaystyle 1\ ft = 0.3048\ m$
So to get the volume in $\displaystyle m^3$, you do this calulcation:
$\displaystyle 12.5 \cdot 15.5 \cdot 8.0\ ft^3 = 12.5 \cdot 15.5 \cdot 8.0 \cdot 0.3048^3\ m^3$
$\displaystyle 1\ m^3 = 1000\ liters$
So you have:
$\displaystyle 12.5 \cdot 15.5 \cdot 8.0 \cdot 0.3048^3 \cdot 1000\ liters$
I think you can handle it from here.
