106 square feet.. your welcome
Okay so first we need to find the height ofn one hay barrel. To do this we must use the equations v= h×w×l
We already know 3 out of the 4 variables in the equations, in this case we are given the volume so we must work backwards.
The equation will look like this:

First we must mulitpy 4 and 1 1/3 to get 16/3. The equation will now look like:

Next divide 16/3 from h then from 10 2/3 to get :

The height is 2ft. Finally multiply 2 by the number of hay barrels (8) placed upon each other becuase we're finding the height and you will get your answer of 16 ft in height.
