Answer: 207

Step-by-step explanation:

To find the surface area, find the area of all the shapes in the three-dimensional figure and then add them.

Find the area of the two triangles first:

1/2*b*h = area of a triangle

1/2* 8* 9= 36

36 is the area of one of the triangles.

Multiply 36 by two because there are two triangles.

=72

Then find the area of the squares/rectangles.

8*5= 40

9*5= 45

10*5 = 50

72+40+45+50

=207
