Each pixel needs to store 1 Byte( 8 bit)

Total 1024 x 1024 pixels

Total storage space = 1024 x 1024 x 1 = 2 10 x 2 10 x 1 = 2 20 = 1 MB

Total memory requirements is 1024 * 1024 *8 bits. to convert it to byte we need to divide by 8 then to kb we need to divide by 1024 and then to mega byte again need to divide by 1024, resulting in 1 value. so the result is 1 Megabyte.
