Question

I don't know how to find the height of the pyramid.

Answer 1

ok... the formula for volume of a pyramid is

\[V = \frac{1}{3} Base.Area \times height\]

the area of the square base is \[A = 3 \times 3 = 9\]

so now you can substitute all your known information

\[12 = \frac{1}{3} \times 9 \times h\]

solve the equation for h... the height

Answer 2

Ok I get it thanks!

Answer 3

Ok @campbell_st I thought I did but the answer I got itsn;t an option..

Answer 4

well

12 = 1/3*9*h

so simplifying 1/3 * 9 = 3

12 = 3*h

whats the value of h

Answer 5

I did that, then would you subtract 3, or divide it?

Answer 6

Oh you divide it, because it can also be written as 3h. That kinda tripped me up into think you would subtract it.

Answer 7

Thanks dude.
