Number of pixels = 5x120 x 7 x 120 = 504000 pixels. Each pixel = 24 bits, hence file size = 12.096 Megabits = 1.512 Megbytes. Each index is 8 bits (256 colors), Hence file size = 50400x8 bits = 0.504 Megabytes. Black, White and Gray has 8 bits per pixel. So file size is = 50400x8 bits = 0.504 Megabytes.
