One byte For each primary color results in 256 different intensity levels for each primary color. Thus a pixel can take on a color from 256X256X256 or 16.7 milion possible choices.
If 1 bit = 256 Color Approximately.
Then in 24 bit = 256 X 24 = 6144 color Approximately.

256, 8 bits per pixel = 2^8 colours.
You can represent a maximum of 2^24 colors in RGB. This equals to 16777216 possible colors.
You are actually asking how many colors are possible in 8 bit per channel. 8 bit per channel means 256 colors, 1 bit= 2 colors, 2 bits= 4 colors, 3 bits= 8 colors, 4 bits= 16... 8bits= 256 colors. Since we have 3 channels in RGB color mode: Red, Green and Blue that means that we have 3x8= 24 bits per pixel in an image. 3x8 also means 256x256x256 colors possible. Number of possible colors in 8 bit per channel or 24 bits per pixel image is 256x256x256 colors or in particular exact number of possible colors is 16777216.
8
Most modern digital cameras use 24 bits (8 bits per primary) to represent a color. But more or less can be used, depending on the quality desired. Many early computer graphics cards used only 4 bits to represent a color.
2^10 * 2^10 * 2^10 102410241024 1,073,741,824
One bit is 2 possible colors, black, 8bit has a possible of 256
A 32 bit per pixel bitmap will have 8 bits each for red green and blue, and 8 bits for alpha level. So 2^24 colors.
30kb = ? pixel?
24 bits/pixel: one byte for red, one byte for green, one byte for blue.
1024bitsIf "Bitmap" refers to a specific entity, image or file: I do not know. But if "Bitmap" refers to a general image then it is 8 bytes or 64 bits per pixel. I just made 3 1*1 bitmap images at colordepths 2bits (monochrome), 8 bits (256 colors) and 24 bits (16 Million colors). The sizes of these images were the same! (surprized me too!) Then I made a 1*2 pixel image and it was 66 bytes (528 bits) so the "overhead Microsoft paint puts on a bitmap is 400 bits. This could be an effect of limitations inherent in Microsoft Paint.
