    Answer:

    Volume = 100 cm³

    ​Surface area of the square pyramid = 145 cm²

    Step-by-step explanation:

    Given:

    Perpendicular height = 12cm

    Square length = 5cm

    Find:

    Volume

    ​Surface area of the square pyramid

    Computation:

    Area of base = side²

    Area of base = 5²

    Area of base = 25 cm²

    Volume = (1/3)(A)(h)

    Volume = (1/3)(25)(12)

    Volume = 100 cm³

    ​Surface area of the square pyramid = A + 1/2(P)(h)

    Perimeter square pyramid = 4(s)

    Perimeter square pyramid = 4(5)

    Perimeter square pyramid = 20 cm

    ​Surface area of the square pyramid = 25 + 1/2(20)(12)

    ​Surface area of the square pyramid = 145 cm²
