You can use the following formula to calculate the surface area of the right rectangular prism:

Where "w" is the width, "l" is the length, and "h" is the height.
Knowing that this right rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.
Then, the surface of the right rectangular prism is:
![\sf SA=[(3 \ cm* 8 \ cm)+( 8 \ cm* 5 \ cm)+(5 \ cm*3 \ cm)]](https://img.qammunity.org/2024/formulas/mathematics/high-school/hd655b6xkibh33ja5ssthjuxpwp26z1gct.png)
