A square coil, enclosing an area with sides 8.3 cm long, is wrapped with 2,545 turns of wire. A uniform magnetic field perpendicular to its plane is turned on and increases to 0.37 T during an interval of 1.6 s. What average voltage is induced in the coil? Express the answer with two decimal places.
