Answer:

Step-by-step explanation:

area of triangular endface = ½×6×8 = 24 cm²

area of rectangular endface = 4×8 = 32 cm²

area of each endface = 24+32 = 56 cm²

area of each 3×10 face = 30 cm²

area of 3×4 face = 12 cm²

area of base = 8×3 = 24 cm²

surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
