@@ End of Day Wrap - Saturday 3/5/14 Sydney, Australia Time 23:30
Hi all,
Great answers today from DavidQD, Admin, CPhill, Rom, Gib, Bertie and of course some anonymous people. Thank you all. ![]()
We noe have an outbox so we can see the messages that we have sent. That's a nice step forward. Other asspects of the members section still need a lot of work. Not to worry, it is comming together slowly. Our top answer board has changed again. The numbers have had another boost. lol Andre has told me that it has 'bug' so I don't know what it will look like tomorrow.
I did send a quick message to Andre. I told him of Alans's observations concerning the member profiles appearing in the answer section. I also asked him if he could run some kind of language scanner through posts so that some of the vulgar ones could be deleted automatically. He hasn't replied yet.
We had an anonymous post signed "Lucifer van Pelt" this morning. It was a lot of fun. Take a look for yourself.

Chris found this one interesting. It might be but it needs to be explained better by the question asker I think. http://web2.0calc.com/questions/arc-and-how-to-find-an-angle
That is about it for this Friday/Saturday.
Enjoy the rest of your weekend.

There were a couple of different definitions. It was a bit confusing.
I think for prism you don't include the two ends and for pyramids you don't include the bottom.
I don't think i have heard the term lateral surface area before.
-------------------------------------------------------------
Now I will look at the first one.
The top and bottom are right angled triangles. They are the same. The sides are 6,8 and 10km
so the area is 2 * (1/2 * 6 * 8) = 2*(24) = 48km2
The other 3 sides are rectangles the total area is (4*6)+(4*8)+(4*10) = 24+32+40=96km2
Total area = 48+96 = 144km2
Lateral area = 96km2
