    115200000 bits

    Explanation:

    Given dа ta:

    Total Time = 3 minute = 3 x 60 sec = 180 sec

    Sampling rate = 40,000 bits / sample

    Each sample contain bits = 16 bits / sample

    Total bits of song = ?

    Solution

    Total bits of song = Total Time x Sampling rate x Each sample contain bits

    = 180 sec x 40,000 bits / sec x 16 bits / sample

    = 115200000 bits

    = 115200000/8 bits

    = 14400000 bytes

    = 144 MB

    There are total samples in one second are 40000. Total time of the song is 180 seconds and one sample contains 16 bits. so the total bits in the song are 144 MB.
