Answer: Area of cross section that is parallel to face CDHG is 432 cm².
Step-by-step explanation:
Since we have given that
There is a cross section that is parallel to face CDHG.
So, Length of cross section would be 36 cm
Width of cross section would be 12 cm.
So, Area of cross section would be
[tex]Length\times breadth\\\\=36\times 12\\\\=432\ cm^2[/tex]
Hence, Area of cross section that is parallel to face CDHG is 432 cm².
