How many bytes 200x100 8 bit image?

A 200x100 image with an 8-bit color depth means each pixel is represented by 1 byte. To calculate the total size, you multiply the width by the height and then by the number of bytes per pixel: 200 pixels * 100 pixels * 1 byte/pixel = 20,000 bytes. Therefore, the image size is 20,000 bytes.
