Answer:
244 in^2
Step-by-step explanation:
We'll start by listing out the dimensions of different surfaces on the shape, and how many times that specific sized rectangle is on the prism.
- 7x2 = 2
- 12x2 = 2
- 12x7 = 2
The prism has six sides, so check that whatever list you make lines up.
- one side is equal to 14 in^2, so both sides have a total area 28 in^2
- one side is equal to 24 in^2, so both sides have a total area of 48 in^2
- one side is equal to 84 in^2, so both sides have a total area of 168 in^2
Now we can add all this up, 28 + 48 + 168 = 244 in^2 !
