Answer:
10 5/12 is the answer, hope this helps
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
(B) first calculate the are of the whole rectangle
Then calculate the area of the two triangles . On top right the height will be 5 ft and the base will be 4 ft
And on the bottom left the height will be 4ft and the base will be 10ft
After calculating the area of two triangles and one rectangle
You need to subtract the are of triangles from the area of the rectangle
And what ever comes will be your answer .
I hope you understood the procedure .
Thanks
