Answer 1

Department 1:-

Each CD stores 12,000 images.

To store 750,852,214 images required CDs

=750,852,214÷12,000

=62,572 CDs

Department 2:-

Each CD stores 12000 images.

To store 1,538,535,515 images CDs required

=1,538,535,515/12000

=128,212 CDs

Department 3:-

Each 15 inch platter stores 1,400,000 images via COLD.

To store 129,956,493,345 images platters required

= 129,956,493,345/1,400,000

=96,827 platter required.

Department 4:-

Each platter stores 14 Gigabytes(GB)

Each image size =199KB.

Total size of 2,000,000 images= 2,000,000 × 199

=398,000,000KBs

=398 GBs(1 GB = 1,000,000 KB)

Platters required = 398/14GB( each platter)

=29 platters
