What is the surface area of the triangular prism whos

Answer 1

e triangular base has a base of 3 inches and a height of 4 inches, and a height of 5 inches?

Surface area of triangular prism = 2(base area) + (perimeter of base)(height of prism)

First, calculate the area of the triangular base:
Base area = (1/2) * base * height
Base area = (1/2) * 3 * 4
Base area = 6 square inches

Next, calculate the perimeter of the triangular base:
Perimeter of base = base1 + base2 + base3
Perimeter of base = 3 + 3 + 5
Perimeter of base = 11 inches

Now, calculate the surface area of the triangular prism:
Surface area = 2(6) + (11)(5)
Surface area = 12 + 55
Surface area = 67 square inches

Therefore, the surface area of the triangular prism is 67 square inches.
