Calculate the sizes of the following uncompressed graphic files.
| Colour Depth bits | DPI | Length (Inches) | Height (Inches) |
| 8 | 600 | 6 | 8 |
| 8 | 300 | 4 | 3 |
| 8 | 75 | 1 | 1 |
| 8 | 600 | 5 | 4 |
| 8 | 300 | 8 | 9 |
| 16 | 600 | 6 | 8 |
| 16 | 300 | 4 | 3 |
| 16 | 75 | 1 | 1 |
| 16 | 600 | 5 | 4 |
| 16 | 300 | 8 | 9 |
| 24 | 600 | 6 | 8 |
| 24 | 300 | 4 | 3 |
| 24 | 75 | 1 | 1 |
| 24 | 600 | 5 | 4 |
| 24 | 300 | 8 | 9 |
Let me get you started, here is the first solution
Calculate the number of Pixels
Pixels = Length X DPI X Height X DPI
=6 x 600 x 8 x 600
=17280000 Pixels
Calculate the number of bits
Bits = Pixels X Colour Depth
=17280000 X 8
=138240000 bits
Convert it to Bytes, KilioBytes, MegaBytes etc
Divide by 8 for Bytes and 1024 for the rest
=138240000/8
=17280000 Bytes
=17280000/1024
=16875 KiloBytes
=16875/1024
=16.4794921875 MegaBytes
It is good practice to round up to 2 decimal places
Answer = 16.48MB
