Answer:
1.152 GB if it will be at 128 kbps quality
Explanation:
So, let's say you choose your mp3 be 128 kbps (kilobits per second).
One byte is 8 bits. So 128 kbps = 16 kilobytes per second.
There is 60*60 seconds in one hour. So 16*60*60 = 57.6 megabytes per hour
Multiply by 20 hours to get your answer: 57.6*20 = 1152 MB = 1.152 GB.
