    Answer: 1,512 cubic inches

    Explanation:

    To get the length of the inner side of the cube, we multiply the thickness by 2 and then, we subtract the result from the outer side of the cube.

    In terms of equation:

    (inner side) = (outer side) - 2 (thickness)

    Since the outer side is 12 inches and the thickness is 3 inches, then the inner side is given by

    (inner side) = (outer side) - 2 (thickness)

    = 12 - 2 (3)

    (inner side) = 6 inches

    Therefore, the amount of metal needed to smelt the cubic box is given by

    (Volume of metal) = (outer side) ³ - (inner side) ³

    = 12³ - 6³

    = 1,728 - 216

    = 1,512 cubic inches
