Answer:
It is C. If a2 + b2 =c2, then the triangle is a right triangle.
Step-by-step explanation:
Triangular Prism- SA= 1/2bh
= 1/2 × 7 × 11
= 38 1/2 × 4 = 154
7 × 7 = 49
= 154 + 49
= 204in³
Rectangular Prism- SA= 2lw + 2lh + 2wh
= 2 × 11 × 7 + 2 × 11 × 7 + 2 × 7 × 7
= 154 + 154 + 98
= 406in³
Therefore, the rectangular prism has the larger surface area.
