    Surface area = 6x^2 + 24x + 24.

    Step-by-step explanation:

    There are 6 faces on a cube.

    Area of 1 face = (x + 2) ^2.

    So the total surface area = 6 (x + 2) ^2

    = 6 (x^2 + 4x + 4)

    = 6x^2 + 24x + 24.

    6 (x+2) ^2

    Step-by-step explanation:

    it has a surface area 6l^2

    where l is the edge length

    l is equal to (x+2)

    , so

    6 (x+2) ^2
