Question

The diagram represents a lamp that Anderson wants to paint. He only wants to paint the lateral sides of the lamp.What is the area of the lateral surfaces that Anderson wants to paint?

Answer 1

Given the diagram of the lamp that Anderson wants to paint, you can identify that it is a rectangular prism.

The formula for calculating the Lateral Surface Area of a rectangular prism is:

`LSA=Ph`

Where "P" is the perimeter of the base and "h" is the height of the rectangular prism.

In this case, you can determine that:

`\begin{gathered} P=6in+4in+6in+4in=20in \\ h=8in \end{gathered}`

Therefore, substituting values into the formula and evaluating, you get:

`LSA=(20in)(8in)=160in^2`

Hence, the answer is: Second option.
