$$ \ce{Al^{3+}(aq) + 3e^- -> Al(s)} \hskip{2em} E^\circ = \pu{-1.66 V} $$ $$ \ce{Ag^+(aq) + e^- -> Ag(s) } \hskip{2em} E^\circ = \pu{+0.80 V} $$

According to the standard reduction potentials given above, what is the standard cell potential for the reaction represented below?

$$ \ce{3Ag^+(aq) + Al(s) -> 3Ag(s) + Al^{3+}(aq)}$$
