### Derec`s Triangular Prism

Triangular Prism
-Five faces
-2 triangles, 3rectangles
-Formula L x W, B x H divided by 2

First you need to find the numbers you need the formula BxH/2

Two triangles
BxH/2
5x6=30/2=15
5x6=30/2=15

Next is LxW
10x12=120
10x12=120
10x12-120
TSA: 15+15+120+120+120=390

1. Good post Derec, It's great you have the writtings for the triangular prism. Next time you should add the picture examples.

2. Good job Derec! Next time you might want to explain what you mean or add some pictures.

3. Not bad Derec. You even bothered to add pictures after you were suggested to. They're a bit blurry, but I can still see it. Oh and,instead of pasting the entire link to the video on the post just paste the embed code when switching to edit HTML.

4. Great post Derec. Next time explain your work more and make your link into a word. Other than that, great job.

5. Good Job! What you might want to do is, maybe later, try to add more explanation, or even the photos of what you had done. Thanks, Derec!
