Answer:
Step-by-step explanation:
1. Approach
The surface area is the two-dimensional space around a three-dimensional object. In other words, if one was going to wrap an object with paper, the surface area is the amount of paper one would need. To find the surface area, one could find the area of each face of the prism and then add up all of the values.
2. Finding the surface area,
To find the area of each face of the prism, one must multiply the length of the face by the width of the face. After doing so, add up all of the resulting values.
10 * 20 = 200
8 * 20 = 160
6 * 20 = 120
* 6 * 8 = 24
* 6 * 8 = 24
Add up all of the values,
200 + 160 + 120 + 24 + 24
= 528
