Answer:
112 units²
Notes to know:
The lateral area and surface area of something are similar, but not the same
-> Surface area is the area of all the sides added up
-> Lateral area is the surface area of all the sides not including the top and bottom
Explanation:
Since this is a rectangular prism, it will have 6 sides in total. That means the lateral area will be a total of four sides.
The sides we need to find for lateral area:
1: 2 * 4 = 8
2: 2 * 4 = 8
3: 12 * 4 = 48
4: 12 * 4 = 48
Add them together:
8 + 8 + 48 + 48 = 112 units²
Have a nice day!
