Can someone pls help me with this problem. '1/2(12)(14)' the 1/2 stands for a fraction.
(1/2) (12) (14) =
6 * 14 =
Hey, thx for the answer but its not fitting the problem. I have to calculate the Surface area of a regular pyramid. the length is 12cm the slant height is 14 cm. so my problem is 1/2 (12) (14) +144 = 480, but I can't seem to solve it.
Here is a picture of a pyramid with its lateral faces laid out.
Remember, you need to get the areas of all four triangles, not just one!
surface area = ( 1/2 )( perimeter of base )( slant height ) + ( area of base )
= ( 1/2 )( 12 * 4 )( 14 ) + ( 12 * 12 )
= ( 1/2 )( 48 )( 14 ) + 144
= 336 + 144
I do not understand what you answer has to do with the question? ,,,,,
It was a response to the second comment:

Thanks Hectictar, I did not see that post you were answering.
I must have had my eyes shut at the time LOL :))
Welcome to the forum "2hot"
Don't worry about people who are rude to you. You always get some of those on forums.
It is good to appologise sometimes, but when people are really rude to you it is better to just totally ignore them. :)
A rude comment with sharp barbs can pierce the ditzy fog that sometimes envelopes intelligent persons. It’s probably better not to totally ignore these, just ignore the rudeness. Perhaps then someone that’s too hot 2 die will not be too dumb 2 live.
Is that really true though? From what I've seen, barbs don't do that good a job at piercing fog.....but shining some warm sunshine on that fog is what really clears it up........
What you say is very true. Unfortunately, I never learned how to control sunshine very well, but I am a near expert at throwing barbs. Perhaps I could learn from you. You seem wise beyond your years. You are also very good at teaching math to the dumb and brain-dead (young and old, if you prefer). I know this to be a fact, because I’ve learned much from your posts.
Damņ you JB! Read your blŏŏdy messages! I told you there were forum members who think your troll posts are my work. You not only imitate Nauseated’s dark passenger, you imitate mine too. I sometimes get hate mail because of it. I don’t mind that much, but I most of the time I have no bleedin' idea what the helļ they’re writing about because I didn’t write the posts and they’ve long been deleted.
There are three blanked posts on this thread, so your snarky and rude comments must have been voluminous; though I am sure they were quite funny, you need to log on and claim your copyright. I don’t want to be your secretary.
Oh! I almost forgot: Hi Melody.
Why should I? I like having a secretary. Girls are good at that kind of thing. Much better than guys are.
Of course we are. Everyone knows that. You would especially know because most secretaries were guys when you were in your prime. I bet you made a great “Boy-Friday.” Tell me, did your boss like sugar in his coffee? Did you sit in his lap when you took dictation?
ROFLMFAO! It depended on the boss whether or not I’d sit in his lap. If he was a hunk and not too frisky I might sit in his lap. As for coffee, one thing none of them liked was having it dumped in their lap. Rumor has it that Jerry Lee Lewis wrote his famous song, Great Balls of Fire, after his secretary dumped hot coffee in his lap.
Really? I thought it was his thirteen-year-old wife, who did that after she tired of taking his dictation. Smart girl!
Jesus, JB what do you want to hide for? This forum has some great mathematicians, but it lacks humorous and articulate trolls. You are the funniest troll on here since Lancelot Link and Nauseated, (besides moi, of course). Quit hiding under your bridge! Come out and play. You can always go back to hiding, when you have a mind to.
I’ll think about it.
Do you really think I am that funny?
I see someone gave me a point, was that you?
Good! You do that. Don’t think too hard, you might overheat your brain.
Well, yes, but looks aren’t everything. Anyway, there’s not exactly a lot of competition on here, but yes, I do. I’m not the only either.
No. the point wasn't from me.
Oh, we are in top form tonight . . .
OK I thought about it. I will, but I want one of your famous banana daiquiris.
Who are the others who like my posts?
Done. I’ll start making it now.
I’ll let your fans introduce themselves.
Great. No peal and no spit.
I have a good idea who one of my fans might be. Hectictar was the only other one on when I got that point. So . . . .
All my daiquiris are no peal and no spit, except for the special, old-fashioned ones that I make for Lancelot.
You shouldn’t jump to conclusions, JB. At your age, you shouldn’t be jumping at all.
Anyway, just because someone likes one of your posts doesn’t mean that person is a fan.
OH no, I’m the one who’s waiting. You log on then I serve you your daiquiri.
I'm going to drink this myself and then log off. It’s starting to melt..
Keep your pantyhose on. I wrote it down somewhere just in case this ever happened.
That rips it, JB. I’m about to fall out of my tree. I’m removing my pantyhose and going to bed!
Oh I just need another minute. But if you are going to do that, I’d like to join you.
I bet you would! Well, I just add your name to the wish list. It’s grown quite long in recent years.
Well, what a wonder to behold. Your daiquiri was melting, so I drank it meself.
I’ll make you another one tomorrow, but only if you log on again.
Hmm . . . somehow, this place seems lonely now.
I broke the thread
