\n" ); document.write( " $\"V+=+s%5E3\"$

\n" ); document.write( "Given V = 2744,
\n" ); document.write( " $\"s+=+2744%5E%281%2F3%29\"$

\n" ); document.write( "Use a calculator if needed.

\n" ); document.write( "Alternatively, you can find the answer with a little bit of estimation and logical reasoning.

\n" ); document.write( "(1) The answer is PROBABLY a whole number.
\n" ); document.write( "(2) 10^3 = 1000; 20^3 = 8000. So the number is between 10 and 20; and closer to 10.
\n" ); document.write( "(3) Of the possible answers 11, 12, 13, and 14, only one of them has units digit 4 when raised to the 3rd power.

\n" ); document.write( "So 14 is the PROBABLE answer; confirm it with a calculator.
