    24 in

    Step-by-step explanation:

    3 x 4 x 2

    (We are assuming that this is for the volume of the whole box.)

    3 x 4 = 12

    12 x 2 = 24

    24 in for the whole volume of this box.

    In case you are figuring out the measurements for one side:

    24/6 = 4

    4 in for one side.

    And, if that is for just 4 sides, then you would multiply by 2 more.

    So:

    3 x 4 x 2 x 2

    24 x 2 = 48 in If the original formula was for just 4 sides.
