taylor0402 · Answer

go to that is gives you the formula

osgood · Answer

Can you just post the formula?

taylor0402 · Answer

ugh fine

taylor0402 · Answer

no thats not what i use

mathmale · Answer

"square pyramind?"   What does the base look like?

osgood · Answer

whats it sound like?

taylor0402 · Answer

dude the formula is in the link

mathmale · Answer

That question was for Osgood.

anonymous · Answer

$\sf L = Pl$

Where $\sf P$ is the perimeter of the base, and $\sf l$ is the slant height.

osgood · Answer

thanks

mathmale · Answer

@greenlegodude57 :  Would you mind quoting some reference?  Where did that formula come from?

mathmale · Answer

Osgood:  What is the formula for the area of a triangle of height h and base x?

osgood · Answer

Why?

mathmale · Answer

I'm checking out that formula given to you by the other user.
Are you interested in accuracy or are you not?

osgood · Answer

the base side of my triangle is 8 and the slant height is 22 the answer I came up with is 704, that does not seem right does it?

anonymous · Answer

No, you did it incorrectly.

anonymous · Answer

$\sf L = Pl$

$\sf L = (8 \times 8)(22)$

mathmale · Answer

"the base side of my triangle is 8 and the slant height is 22"

@Osgood:  What is the area of ONE of the four lateral sides?  Mind showing your work?

osgood · Answer

I found out how to do it ( friend showed me )

mathmale · Answer

Glad you've found the correct answer.  Unfortunately, that formula L=PI is not correct.  That's why I asked you to work with me to develop a valid formula for the lateral area of that square pyramid of yours.

osgood · Answer

I realized it was not right, I found this formula in my school 4(1/5*Base*slant height)
