Explanation:
Detailed explanation-1: -The number of bits devoted to an individual pixel determines the number of colors that can be assigned to that pixel. For example, if each pixel is represented by 4 bits, then a given pixel can be assigned one of 16 different colors (2^4 = 16).
Detailed explanation-2: -1. Multiply the width and height of the image, in pixels, to get the total pixel count. 2. Multiply the total pixel count by 3 to get the image size in bytes.
