    There would be 256 bacteria after one day.

    There are 24 hours in a day, and the amount of bacteria doubles every 3 hours, so it will double:

    24 / 3 = 8 times.

    To find the current amount we could use an equation such as:

    1 * 2^8 = x

    Finally, solve for the number of bacteria:

    1 * 2^8 = x

    1 * (2 * 2 * 2 * 2 * 2 * 2 * 2 * 2) = x

    1 * (4 * 4 * 4 * 4) = x

    1 * (16 * 16) = x

    1 * 256 = x

    x = 256
