Answer:
The total surface area of the figure is 516 square units.
Step-by-step explanation:
The net of the triangular prisms is attached. Remember, the total surface area refers to the area of each face of the volumetric figure. In this case we have 3 equal rectangles and 2 equal triangles.
- The Area of the rectangles.
- A^1 = 3 (10 x 14) = 3 (140) = 420 u^2
2. The Area of the triangles.
- A^2 = 2(1/2 x 12 x 8) = 96 ^2
The total surface area is given by the sum of all these areas:
S= 420 + 96 = 516 u^2.
