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
