Answer:</h2>
<u>Total surface area = 624 + 56 =</u><u> 650 cm²</u>
<h2>
Step-by-step explanation:</h2>
The given prism has 2 triangles and 3 rectangles. we will find the surface area of individuals and then add them
So the area of triangles is (length x height)/2 which will be
Area of triangles = 8 x 7 = 56/2 = 28
Since there are two triangles so 28 x 2 = 56
Now
Area of rectangles is length x width
Area of rectangles= 26 x 8 = 208
Since there are 3 rectangles so 208 x 3 = 624
Total surface area = 624 + 56 = 650 cm²
