Question

The figure is the net for a rectangular prism. What is the surface area of the rectangular prism represented by the net? Enter your answer in the box. _______in^2

Answer 1

Answer: 174 in²

Step-by-step explanation:

The surface area of the rectangular prism is the sum of the surface areas of the rectangles.

The formula for calculate the surface area of a rectangle is:

Where l is the lenght and w is the width.

As you can see in the figure, there are three pairs of equal rectangles, therefore, multiply the surface area of one rectangle of each equal pair by 2.

The surface area of the rectangular prism is:

Answer 2

Answer: 174 in²

Explanation:

The surface area of the rectangular prism is the sum of the surface areas of the rectangles.

The formula for calculate the surface area of a rectangle is:

`A=l*w`

Where l is the lenght and w is the width.

As you can see in the figure, there are three pairs of equal rectangles, therefore, multiply the surface area of one rectangle of each equal pair by 2.

The surface area of the rectangular prism is:

`A=2(9in*5in)+2(9in*3in)+2(5in*3in)=174in^(2)`
