Actually Welcome to the Concept of the Polygons.

Since we can see, after assembling it becomes as prism like structure, so it's a

a.) Triangular Prism Polyhedron

b.) area of this Polyhedron is given as,

(area of triangle ×2)+(area of rectangle 1)+(area of rectangle 2)+(area of rectangle 3)

=> (1/2×8×6×2) + (6×5)+(8×5)+(10×5)

=> (48)+(30)+(40)+(50)

=>(48)+(120)

=>168 sq. units

Area = 168 sq. units

unless if u could do my questions, if not i wouldn't want to
