Answer:

The answer to your question is 204 cm²

Step-by-step explanation:

Process

1.- Calculate the area of the first rectangle from up.

Area = base x width

        = 10 x 5

        = 50 cm²

2.- Calculate the area of the middle rectangle

Area = 10 x 8

        = 80 cm²

3.- Calculate the area of the lowest rectangle

Area = 10 x 5

        = 50 cm²

4.- Area of the rectangular faces

Area = 50 + 80 + 50

        = 180 cm²

5.- Calculate the area of the triangles

Area = base x height / 2

        = 8 x 3 /2

        = 24/2

        12 cm²

6.- Area of the triangles

Area = 12 + 12

        = 24 cm²

8.- Total area

Total area = 180 + 24

                 = 204 cm²
