Answer:
144 cm²
Step-by-step explanation:
A prism's surface has 2 triangles & 3 rectangles.
In both the triangles , length of :
Perpendicular = 4 cm
Base = 6 cm
So , Area of both triangles = 
In the 3 rectangles ,
Length = 8 cm
Width = 5 cm
So , Area of the rectangles = 
Hence the total surface area of the prism is = 120 + 24 =144 cm²
