Answer:

Surface area = 207 cm²

Explanation:

Surface are of triangular prism = 2×BA + P × H

Base Area (BA) = ½*bh

b = 8 cm

h = 9 cm

BA = ½*8*9 = 36 cm²

Perimeter of triangular base (P) = 8 + 9 + 10 = 27 cm

Height for prism (H) = 5 cm

Surface area = 2 × 36 + 27 × 5 = 72 + 135

Surface area = 207 cm²
