To determine the surface area of the glass surfaces, we will determine the area of each rectangle and sum them.

The area of a rectangle is given by the following formula:


A=legth*width.

Now, the rectangles that compose the total surface area of glass have dimensions:


32in*12.75in,\text{ 32in}*19in,12.75in*19in.

Therefore, the total area adding up the areas of the rectangles is:


A_t=32in*12.75in+2*12.75in*19in+2*32in*19in.

Answer part a:


2108.5in^2.

Now, the area covered by the plastic lid is the area of a rectangle of dimensions


32in*12.75in.

Therefore, the surface area of the plastic surface is:


408in^2.

Answer part b:


408in^2.
