Answer:
82
Step-by-step explanation:
To find the surface area, split the figure into each regular shape. Find the area of each surface and add the areas together.
Area of a Triangle (2 surfaces):
A = 0.5*2*5 = 5
For both surfaces, the area is 10.
Area of a quadrilateral (2 different surfaces):
A = 6*3 = 18
A = 5*6 = 30
A = 4*6 = 24
All together the three surfaces have area 18+30+24 = 72.
The surface area of the entire figure is 10 + 72 = 82
