Question

What's the surface area of this shape

Answer 1

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.
