if we concentrate on the triangle
|dw:1441660064080:dw|

So 5 squared + 13 squared = h squared?
That would be 194 = h squared. DO I dived 194 by 2 now?

divide*

you could type
h^2 +5^2 = 13^2
5^2 means 5*5
13^2 means 13*13

Ok. Thanks! Lol and then once you solve that you do it exactly like the last problem we did?

yes. what do you get for h^2 ?

h^2+5^2=13^2
h^2=13^2-5^2
h^2=144
144/2=72
Did I do that right?

h^2=144
ok. now take the square root of both sides. (h^2/2 does not "undo" the square)

the idea is \( \sqrt{h^2 } =h \)
so we do that to both sides

I did the sqare root of 144 on my calcalator and I got 12.

yes, h=12
as a check you can do
5^2 + 12^2 and it should give 13^2 (and it does)

Ok I have one more question to post. I hope I'm not bothering you!

what did you get for the volume. (it would be a shape to make a mistake now)

1200?

what is the formula for the volume of a pyramid?

1/3BH

put in numbers for B and h

Oh it's 400. I forgot to put the 1/3 when I first did it

yes, 400

That would have been a simple mistake lol Thanks
