<PRE><B>Question 1006341</B>
1 foot is 12 inches, but you use this three times because you have a cubic measure to convert.


{{{(1*foot^3)(12/1)(inches/foot)(12/1)(inches/foot)(12/1)(inches/foot)}}}


{{{1728((inches)^3/(foot)^3)}}}------this is the conversion ratio to use.


--

You want to keep three significantg figures in the final answer.


{{{(5.56*10^7)(feet^3)(1728)(inch^3/feet^3)}}}


{{{(5.56*10^7*1728)inch^3}}}


{{{(5.56*1728*10^7)inch^3}}}


{{{9607.68*10^7*inch^3}}}


{{{9.60768*10^3*10^7*inch^3}}}


{{{9.60768*10^10*inch^3}}}


{{{highlight(9.61*10^10*inch^3)}}}, correcting for the accuracy of the given numbers
