Answer 2

hint:
we can apply this formula:
\[V = \frac{{Sh}}{3}\]
where \(h=10\) cm, and \(S\) is the area of the base, which is the triangle, whose sides are \(12,\;16\) cm
namely, I'm thinking this:

Answer 3

oops.. I have ade an error, here is the right formula:
\[V = Sh\]

Answer 4

so, we have:
\[S = \frac{{12 \times 16}}{2} = ...?\]

Answer 5

please continue

Answer 6

oops.. I have made*...

Answer 7

Um, so what is going on here I was in my phone sorry? All these errors???

Answer 8

as I wrote before, the right formula, is:
\[V = Sh\]
where:
\[S = \frac{{12 \times 16}}{2} = 96\;c{m^2}\]
and \(h=10\) cm
therefore:
\[V = Sh = 96 \times 10 = ...?\]

Answer 9

so, what is the right option?
