Answer 1

please help me

Answer 2

The first three choices have a 1/3 in them. The answer looks like it's the last one.

Answer 3

ok

Answer 4

but the last one is v=1/3 pi2h

Answer 5

so they all have 1/3

Answer 6

The volume of a square-base pyramid is:
\[\Large V = \frac{1}{3}{b^2}h\]
Where b is any one of the side lengths of the pyramid's base (since it's square, they're all the same), and h is the height.
So assuming:
\[\Large \begin{array}{l}
{\rm{v}} = {\rm{1}}/{\rm{3s2h}}\\
= {\rm{v}} = {\rm{1}}/{\rm{3}}{{\rm{s}}^{\rm{2}}}{\rm{h}}
\end{array}\]
Where s is a side length, then that's the formula.
