Question

Please help Find the surface area of the rectangular prism. 7in, 12in, and 2in.

Answer 1

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.

1. 7x2 = 2
2. 12x2 = 2
3. 12x7 = 2

The prism has six sides, so check that whatever list you make lines up.

1. one side is equal to 14 in^2, so both sides have a total area 28 in^2
2. one side is equal to 24 in^2, so both sides have a total area of 48 in^2
3. 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 !
