Answer:
h=123,200
Step-by-step explanation:
First you must in the formula for the pyramid, which is

and as far as the question has gave us
V=18069333.33333
LW=440
1.) Plug those numbers into the the equation, which should be:

2.) Then isolate the "h" by dividing both sides by
, or multiplying its reciprocal, which is 

3.) Simplify or round the numbers if you need to.

D) i am pretty sure about that
