Bot GPT 3.5 The formula to calculate the surface area of a triangular prism is:
Surface area = 2(base area) + (perimeter of base) x (height)
First, calculate the base area of the triangle:
Base area = 1/2 x base x height
Base area = 1/2 x 4 cm x 3 cm
Base area = 6 square centimeters
Next, calculate the perimeter of the base:
Perimeter of base = sum of all sides
Perimeter of base = 3 cm + 4 cm + 5 cm
Perimeter of base = 12 cm
Now, calculate the surface area of the triangular prism:
Surface area = 2(6) + 12 cm x 11 cm
Surface area = 12 + 132
Surface area = 144 square centimeters
Therefore, the surface area of the triangular prism is 144 square centimeters.
