A package is in the shape of a triangular prism. The bases are right triangles with perpendicular legs measuring 9 centimeters and 12 centimeters. The distance between the bases is 10 centimeters.


What is the surface area of the triangular prism?


210 square centimeters

318 square centimeters

360 square centimeters

468 square centimeters

Answer 1

Answer:

Step-by-step explanation:

Area of base = 0.5×9×12 = 54 cm²

Hypotenuse of base = √(9²+12²) = 15

Lateral surface area = 10(9+12+15) = 360 cm²

Total surface area = 2×54 + 360 = 468 cm²
