Is it A or is it B?
OpenStudy (anonymous):
you have to times all those number to get d
geerky42 (geerky42):
\(V = \dfrac{1}{3}Bh\)
You need to find area of base. should be easy, right?
geerky42 (geerky42):
So you got it? @undeadknight26

I got B still :/
Im using the formula L = (lwh)/3
undeadknight26 (undeadknight26):
I understand its D though lol
undeadknight26 (undeadknight26):
Just want to know how to get that answer XD
geerky42 (geerky42):
No it's not D.
geerky42 (geerky42):
and what you used, it's formula for square pyramid.

geerky42 (geerky42):
you have pyramid with right triangle base.
undeadknight26 (undeadknight26):
I see so you would have to divide the base in half?
geerky42 (geerky42):
after multiplying lenghts, yeah
geerky42 (geerky42):
so you should do \(\dfrac{1}{2}(15\times26)\)
undeadknight26 (undeadknight26):

geerky42 (geerky42):
so what's area for base?
geerky42 (geerky42):
correct. now multiply heihgt
geerky42 (geerky42):
then divide whole thing by 3.
geerky42 (geerky42):
So what's final answer?
undeadknight26 (undeadknight26):
