The shortest way is to write the inverse proportion


    P%5B1%5D%2FP%5B2%5D = V%5B2%5D%2FV%5B1%5D,  or  6%2F7 = x%2F251.


From the proportion,  find the unknown volume  x = %286%2A251%29%2F7  cubic inches.


Use your calculator.

My response :   This forum is constructed in the way that i  CAN  NOT  identify from whom I got the message/(the  "comment").

Therefore,  when I get the comment from the visitor in this way,  I simply  DON'T  KNOW  to whom to answer.

If you really want to get the response from me to your message/"comment",
then place the problem's ID number to your message/comment.

It is the only way to support a  two-sides/(two-ways)  dialog.
