Answer:
194 cm squared
Step-by-step explanation:
The prism is made of 5 shapes: 2 large rectangles, 2 triangles, and 1 medium rectangle.
To find the surface area, find the area of each surface and add them together.
2 large rectangles that measure 10 by 6. So the area is 60. For 2 it will be 2*60 = 120.
2 triangles that measure 4 by 6. So the area is 1/2*4*6 = 12. For 2 it will be 2*12 = 24.
1 medium triangle that measures 5 by 10. So the area is 50.
The total surface area is 120 + 24 + 50 = 194.
