“What is the bandwidth of an FM wave with a carrier frequency of 400kHz, modulating frequency of 10kHz, and the maximum deviation of 30kHz?”

Doesn’t matter what the parameters are — the bandwidth of an FM signal is infinite (hooray for Bessel functions!). Fortunately, you can throw some of the outliers away without causing too much damage to the signal. When you restrict the bandwidth, however, you wind up with amplitude modulation to some extent, which hopefully will be wiped off by the limiter in the receiver.
