The surface area of the right triangular prism is 797 square m option second is correct.
What is a triangular prism?
When a triangle is, stretch it out to produce a stack of triangles, one on top of the other. A triangular prism is the name given to this novel 3D object.
We have given a right triangular prism in the picture:
Surface area of right triangular prism = 2(area of the right triangle) + areas of rectangle
= 2(9×15)/2 + 15×16 + 9×16 + 17.4×16
= 135+240+144+278.4
= 797.4 ≈ 797 square m
Thus, the surface area of the right triangular prism is 797 square m option second is correct.
