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

Ok I get it thanks!

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

campbell_st · Answer

well 

12 = 1/3*9*h

so simplifying     1/3 * 9 = 3

12 = 3*h 

whats the value of h

anonymous · Answer

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

anonymous · Answer

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