Solution:

Note that:

  • Surface area = Area of all faces

Finding the area of the two triangles

  • 2(1/2 x 8 x 6)
  • => 8 x 6
  • => 48 ft²

Finding the area of rectangle₁

  • 12.6 x 10
  • => 126 ft²

Finding the area of rectangle₂

  • 12.6 x 6
  • => 75.6 ft²

Finding the area of rectangle₃

  • 12.6 x 8
  • => 100.8 ft²

Finding the surface area of the figure

  • 48 + 126 + 75.6 + 100.8
  • => 350.4 ft²

good job
