Answer:

The surface area of the lower rectangle is 20cm x 4cm= 80 square cm

the surface area of the two triangles is 12 square centimetres

the surface area of one of the top rectangular faces is 20×5= 100 square centimetres

the surface area of the other is 20×3= 60 square centimetres

80+12+60+100=252 square centimetres is the surface area of the polyhydron

Step-by-step explanation:

Remember that in the geometric serie if | r | < 1 the serie converges and if | r | ≥1 the serie diverges.
