    Base area of the triangular pyramid is 96 square units.

    Lateral surface area of the triangular pyramid is 221.6 square units.

    Surface area of the triangular pyramid is 317.6 square units.

    Step-by-step explanation:

    Base area = 8 x 12

    = 96 square units

    Base area of the triangular pyramid is 96 square units.

    Lateral surface area = 2[ (1/2) 10x 14] + (1/2) (12 x 13.6)

    = 2 (70) + 81.6

    = 140 + 81.6

    = 221.6 square units

    Lateral surface area = 221.6 square units

    Lateral surface area of the triangular pyramid is 221.6 square units.

    Surface area = 221.6 + 96

    = 317.6 square units

    Surface area of the triangular pyramid is 317.6 square units.
