What is the surface area of the triangular prism? Round the answer to the nearest tenth. (1 point) 8 cm, 8 cm, 8 cm, 6.9 cm 6 cm

Answer 1

The formula to calculate the surface area of a triangular prism is 2*(base area) + (perimeter of base*height).

First, calculate the base area of the triangular prism:
Base area = (1/2)*base*height
Base area = (1/2)*8*6.9
Base area = 27.6 cm²

Now, calculate the perimeter of the base:
Perimeter of base = 8 + 8 + 6.9
Perimeter of base = 22.9 cm

Now, plug these values into the surface area formula:
Surface area = 2*(27.6) + 22.9*8
Surface area = 55.2 + 183.2
Surface area = 238.4 cm²

The surface area of the triangular prism is approximately 238.4 cm².
