    Juan will have 3 digits after decimal.

    Step-by-step explanation:

    A number having one digit after decimal when multiplied by another number having single digit after decimal, we get a number having two digits after decimal.

    Example:

    0.2 * 0.6 = 0.12

    0.3 * 0.3 = 0.09

    Now we have to find the volume of a box having dimensions 7.2 units by 8.4 units by 12.8 units.

    Volume = 7.2*8.4*12.8 [Each number having one digit after decimal]

    = 774.144 unit³ [Number with 3 digits after decimal]

    Therefore, Juan will have 3 digits after decimal in the final answer.
