Question

A. find the surface area of the glass surfaces of the fish tank B. Find the surface area of the plastic surface of the fish tank

Answer 1

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.`
