Question 1204245
.
<pre>

To start, you should find the total volume. For it, you should multiply

    4 * {{{1/3}}} * 3000 = 4000 cu ft.   (not 3960, which is your value, by mistake !)



      So, the total volume of 8 equal parts is 4000 cu ft.



Next your step is to find the volume for each of 8 parts.


For it, OBVIOUSLY, you should divide 4000 by 8.


The steps that follow are so obvious that I will not go in further details.


Nevertheless, if you have questions, do not hesitate to ask.
