8 0

Answer:

197

Step-by-step explanation:

You have 6 sides of this object. So we will calculate six surface areas.

P1=5x5=25 ( on the top)

P2=9x5=45 ( on the bottom)

P3= 5x5= 25 (left side)

P4=6,4x5=32 (rightside)

P5= (9+5)x5/2=70/2=35 ( front trapeze)

P6=P5=35 ( behided trapeze)

P= p1+p2+p3+p4+p5+p6=

25+45+25+32+35+35 =197
