Hello!
To find the height of a rectangular pyramid, you use the formula h=3(v/lw)
h= height (what we're trying to find)
v= volume
l= base length
w= base width

So, if you plug in everything, you'll see that the height is 14.
Want to check that you're correct? Use the formula V=lwh/3 to see if you get the same volume as before.

If you plug it in, you'll see that it's the same volume as before, so we have now found, checked, and proven the answer is 14!<span />
