Three polarizing filters are stacked, with the polarizing axis the second and third filters at angles of 29.0° and 61.0°, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 55.5 W/cm² after it passes through the stack. If the incident intensity is kept constant but the second polarizer is removed, what is the intensity of the light after it has passed through the stack? Express your answer with the appropriate units.
