parthkohli · Answer

Volume of a square pyramid is $\Large {1 \over 3}b^2 h$
Does that help?

parthkohli · Answer

Another way to think - 1/3 x base area x height

parthkohli · Answer

$ \color{Black}{\Rightarrow 26.97 = \large {1 \over 3}(3)^2h }$

anonymous · Answer

how do i find the height ?

parthkohli · Answer

You first find 1/3 x 3^2, then divide that from both sides, which leaves h on one side.

parthkohli · Answer

What is 3^2? @Senior012

anonymous · Answer

In simple way, h = (3*Volume)/b*b...

anonymous · Answer

so is my final answer 9 ?

parthkohli · Answer

No...

anonymous · Answer

Yes you are right..

parthkohli · Answer

$ \color{Black}{\Rightarrow 26.97 = \large{1 \over 3}(9)h }$

anonymous · Answer

Friend, simply divide 26.97 by 3, you will have your answer...
