Answer:
12,000,000 bytes.
Explanation:
If we want to store an uncompressed binary image, assuming that we will use 256 different levels to represent all tones in a monochromatic image, each pixel will be stored as an 8-bit sample, i.e. one byte per pixel.
The complete image will have 4000 pixels wide by 3000 pixels height, so an entire image will need 3000*4000= 12,000,000 pixels.
As we will use 8 bits= 1 Byte per pixel, we will need to store 12,000, 000 bytes for a complete uncompressed monochromatic (white & black) image.
