    360mm^2

    Step-by-step explanation:

    Surface area of a square pyramid = Base area + Lateral area

    Base area=10mm * 10mm

    =100mm^2

    Lateral area = (4) * (1/2) * (10) * √ (12) ^ 2 + (5) ^ 2)

    = 260 mm^2

    Surface area = Base area + Lateral area

    =100mm^2 + 260mm^2

    = 360mm^2
