Given:

  • Triangular prism

To find:

The surface area of the given triangular prism.

Solution:


sa = bh + ( b_(1) + b_(2) + b_(3))l


sa = 12(5) + (5 + 12 + 13) * 10


sa = 60 + (30)(10)


sa = 60 + 300


sa = 360 \: {m}^(2)

Hence, the surface area of the given triangular prism is 360 square meters.
