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.

I'm sorry. I was gonna put it in the question but I was really busy at the time and since I put it as a response I thought that would be enough. Pls forgive me.

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

                      =  480                        smiley

It was a response to the second comment:

 

" 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. "

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........ smiley

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.frown

 

Oh! I almost forgot: Hi Melody.smiley

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?indecision

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.

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.

All my daiquiris are no peal and no spit, except for the special, old-fashioned ones that I make for Lancelot.smiley

 

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.
