surface area of triangular prisms practice answers

Answer 1

To find the surface area of a triangular prism, you can use the formula:

Surface Area = 2(Base Area) + (Perimeter of Base x Height)

Here are the practice answers for finding the surface area of triangular prisms:

1. Given a triangular prism with a base area of 15 square units, a perimeter of the base as 12 units, and a height of 8 units:
Surface Area = 2(15) + (12 x 8)
Surface Area = 30 + 96
Surface Area = 126 square units

2. Given a triangular prism with a base area of 20 square units, a perimeter of the base as 14 units, and a height of 10 units:
Surface Area = 2(20) + (14 x 10)
Surface Area = 40 + 140
Surface Area = 180 square units

3. Given a triangular prism with a base area of 25 square units, a perimeter of the base as 16 units, and a height of 12 units:
Surface Area = 2(25) + (16 x 12)
Surface Area = 50 + 192
Surface Area = 242 square units

These are the practice answers for finding the surface area of triangular prisms using the given formula.
