Good morning, I got a question like this-

"A hard drive has 6 platters, each platter records data on both sides. There are 3000 tracks of nine sectors each. Each sector stores 512 bytes of data. How many read/ write heads are there and what are the capacity of the drive(in Gigabytes)?"

I understand so far the read/ write heads= 2*6 =12

The capacity of the drive= 512*9*3000*12=165888000bytes

I understand to where they got this answers but its not finish as I need to get it to the gigabyte and this find the capacity of the disk. Can you please assist I don't understand ?
