The length of the prism, l=32 in.
The width of the prism, w=12.75 in.
The height of the prism, h=19 in.
The total area of the prism is,
[tex]\begin{gathered} A=2(lw+lh+hw) \\ A=2\times(32\times12.75+32\times19+19\times12.75) \\ A=2516.5ft^2 \end{gathered}[/tex]
Since the top is covered by plastic lid, the surface area of the glass portion is,
[tex]\begin{gathered} a=A-lw \\ a=2516.5-32\times12.75 \\ a=2108.5ft^2 \end{gathered}[/tex]
Therefore, the area of the glass portion is 2108.5 square feet.
