How to find the surface area of an octagonal prism
Use the formula 2 times base area + Lateral area

Step 1. In order to find the base area you will need to find the apothem using the central angle and then trig to find the apothem.

Step 2. Plug the apothem into 1/2apothem*perimeter for the base area
Step 3. Multiply the Perimeter times height for your lateral area

Step 4 Add step 2 ( base area)and step 3 ( Lateral area)for your surface area
