How many colors can you use to store a 350×200 pixel image as much as possible if the video memory page is 65 KB?

Let’s determine the total number of pixels this image will contain if from the condition of our problem we know for sure that its dimensions are 350 by 200 pixels:

350 * 200 = 70,000.

Let’s determine how many bits will fall on one pixel (bit depth of color), if from the condition of our task we know for sure that the amount of video memory is 65 kilobytes:

65 KB = 65 * 1024 * 8 = 532480;

532480: 70,000 ≈ 7.

Let’s define the number of colors:

N = 2i;

N = 128.

Answer: Number of colors (N) = 128.
