Answer:
The surface area of the prism is 252 square units.
Step-by-step explanation:
The prism has 5 faces.
Surface of the face on the left = 8*8.5 = 68 square units (it is a rectangle)
Surface of the face on the rigth = 10*8.5 = 85 square units (it is a rectangle)
Surface of the face on the botom = 6*8.5 = 51 square units (it is a rectangle)
Surfaces of the faces on the front and the back = 6*8/2 = 24 square units (they are triangles)
Total surface = 68 + 85 + 51 + 2*24 = 252 square units
