Decreasing cube. Each of the three dimensions of a cube with sides of length s centimeters is decreased by a whole number of centimeters. The new volume in cubic centimeters is given by V(s) = s^3 -13s^2 +54s - 72.
\n" ); document.write( "a) Find V(10).
\n" ); document.write( "Sub 10 for s
\n" ); document.write( "V(10) = 10^3 - 13*10^2 + 54*10 - 72
\n" ); document.write( "V(10) = 1000 - 1300 + 540 - 72
\n" ); document.write( "V(10) = 1540 - 1372 = 168 cc
\n" ); document.write( "---------------------
\n" ); document.write( "b) If the new width is s - 6 centimeters, then what are the new length and height?
\n" ); document.write( "The product of L x H = (s^3 -13s^2 +54s - 72)/(s-6) = s^2 - 7s + 12
\n" ); document.write( "Since that's integers, that's (s-3)*(s-4). There's no way to know which is L and which is H.
\n" ); document.write( "c) Find the volume when s = 10 by multiplying the length, width, and height.
\n" ); document.write( "-------------------
\n" ); document.write( "?? Wasn't that part a? Maybe it means:
\n" ); document.write( "(10-6)*(10-3)*(10-4)
\n" ); document.write( "= 4*7*6
\n" ); document.write( "= 168 cc
\n" ); document.write( "Must be, it matches.
\n" ); document.write( "
\n" ); document.write( "
\n" );
