Answer 1

Answer:

162 m^2

Step-by-step explanation:

Tops:  

 The area of the high top is 3*2 = 6

The area of the lower top is 5*2 = 10

                                                        --------

                                                           16

Bottom:

The area of the bottom is 8*2 =16

Back:

The area of the back is 2*11 = 22

Front:  

The top front is 9*2 =18

The bottom front is 2*2 =4

-------------------------------------------

                                           22

Sides

The area of the left side is

               vertical piece  11*3 =33

                 horizontal piece 5*2 = 10

                                                      -------------

                                                           43

The right side is the same = 33+10 = 43

Add them together

top+bottom+ back+front+left+right

16+16+22+22+43+43 =162 m^2
