Answer:
984 cm²
Explanation:
Surface area of triangular prism:


nb is the base of the triangle. b= 10 cm
h is the altitude of the triangle. h = 12 cm
s₁, s₂, s₃ are the sides of the triangle. s₁ = 13 cm, s₂ = 13 cm, s₃ = 10 cm
l is the length of the prism. l = 24 cm
Surface area = 10*12 + (13 + 13 + 10) * 24
= 120 + 36* 24
= 120 + 864
= 984 cm²
