Answer:

144 cm²

Explanation:

The figure given above is a prism with triangular bases.

The surface area of a prism = 2 × area of the base (B) + perimeter of the base (P) × height of the prism (h)

Area of the base = ½ × 4 × 3 = 6 cm²

Perimeter of base = 4 + 3 + 5 = 12 cm

Height = 11 cm

Surface area of prism = 2(6) + 12 × 11

= 12 + 132 = 144 cm².

Surface area of the prism = 144 cm²
