    8 x 10 = 80 inches squared (one side)

    3 x 8 = 24 inches squared (one side)

    3 x 10 = 30 inches squared (one side)

    80 + 24 + 30 = 134 inches squared (three sides)

    Double that for all 6 sides. 2 x 134 = 268 square inches.

    The answer is D.

    SA = 2 (wl + hl + hw)

    SA = 2 ((3) (10) + (8) (10) + (8) (3))

    Multiply:

    SA = 2 (30 + 80 + 24)

    Add:

    SA = 2 (134)

    Multiply:

    SA = 268
