    Step-by-step explanation:The surface area of a square pyramid = 1/2 * slant height * base perimeter + area of base

    The slant height is 8 cm

    The base perimeter is 4 * 5 cm = 20 cm

    The area of the base is 5 cm * 5 cm = 25 cm**2

    Plugging into the formula the area =

    1/2 * 8 cm * 20 cm + 25 cm**2 =

    4 cm * 20 cm + 25 cm**2 =

    80 cm**2 + 25 cm**2 = 105 cm**2
