An image is 3072 pixels by 2304 pixels. Calculate the following:

  1. Total number of pixels.
    • 3072 * 2304
    • 7077888 pixels
  2. Number of bytes occupied this file, assume each pixel uses 3 bytes.
    • 3 * 7077888
    • 21233664 bytes
  3. File size of the image in MB if the original image was reduced by a factor of 5.
    • 21233664 / 5
    • 4246732.8 bytes
    • 4.24 MB
  4. How many uncompressed files of the size calculated in part 2 could be stored in a 4GB memory card?
    • 4GB / 21233664 bytes
    • (4 * 1024 * 1024 * 1024) / 21233664
    • 202
