Answer:
1080 cm
Step-by-step explanation:
To find the surface area, you must find the area of each shape then add all of them together which will give you the surface area.
First, multiply the big rectangle on the top which is: 14cm x 26cm= 364
Next find the area of the triangles which is: 24cm x 10cm= 240/2= 120
Since there is two triangles, u must multiply 120 by 2 which is 240
the rectangle from behind is 10cm x 14cm= 140cm
and the last rectangle on the bottom is 14cm x 24cm= 336cm
Now you must add all of these together: 364 + 240 + 140 + 336 which is 1080.
