Area of opposite sections will be same.

So area of horizontal sections,

                                                     =\frac{1}{2}\times4(16+24) = 2(40) = 80\ cm^2

And area of vertical sections,

                                                     = \frac{1}{2}\times8(20+28) = 4(48) = 96\ cm^2
