You calculate the volume of an pyramid as $\displaystyle V= \frac{1}{3} \cdot A \cdot h$

where A is the area of the base, h the height of the pyramid and V the volume.

Put the values you know in the formula above:

$\displaystyle 72= \frac{1}{3} \cdot 36 \cdot h$ and solve for h:

$\displaystyle \frac{3 \cdot 72}{36}= h$ and you'll get h = 6.
