Answer:
Surface area of the triangular prism = 368 m²
Step-by-step explanation:
Surface area of the triangular prism = Area of the triangular bases + Area of the lateral sides
Area of the triangular base = [tex]\frac{1}{2}(\text{Bases})(\text{Height})[/tex]
= [tex]\frac{1}{2}(12)(8)[/tex]
= 48 m²
Area of the lateral sides = (Perimeter of the base) × Height
= (10 + 10 + 12)×10
= 320 m²
Surface area of the triangular prism = 320 + 48
= 368 m²
Therefore, surface area of the triangular prism = 368 m²
