October 5, 2010Hi guys
So I was assigned to do question 5 a) of the textbook. Here it goes.
By the way, I might have done it a little differently. But as Backe had said, we're all going to Polo Park. It doesn't matter how we get there, as long as we all end up there. So,
As you can see, I've labeled the faces of this prism. A number for each face. (face 1, face 2, etc) Btw, sorry for the awful quality. Pretty much all I did was I calculated the surface area of each face, and then added them together at the end to find the total surface area. If this confuses you, there is an example and explanation of how this method works in page 28 of our textbook.
Now I made a chart to show the calculation for each faces. I hope you are able to follow. Feel free to ask me if it's really that confusing.
In case you didn't get the measurements, the distance between dots is 2 cm, not 1. When I checked at the back of the textbook for the answers, I found that the answer stated there is 216 cm² which is exactly half of the answer that I got. I think it may be that they've forgotten that each distance from dot to dot is 2 cm instead of 1. Or maybe I did something wrong, so tell me. That's all.
