The surface area of the right triangular prism = 720 in²
What is the Surface Area of Triangular Prism?
Surface area of triangular prism = (Perimeter of the triangular base × length of the prism) + (2 × triangular base area)
= (S1 +S2 + S3)L + (bh)
Thus:
- S1 = 13
- S2 = 13
- S3 = 24
- L = 12
- b = 24
- h = 5
Substitute
Surface area of triangular prism = (13 + 13 + 24)12 + (24)(5)
Surface area of triangular prism = 720 in²
