Algebra.Com's Answer #144108 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! If each edge is a: \n" ); document.write( "surface area = 6a^2 \n" ); document.write( "Volume = a^3 \n" ); document.write( "The rate of change of the volume = 3a^2 \n" ); document.write( "That's 1/2 of the surface area. \n" ); document.write( "-------------------- \n" ); document.write( "A number is given for the rate of change, 0.2 cm/sec, but no value for the length of the side, so a numerical answer is not possible. \n" ); document.write( "The answer doesn't match any of the choices. I suspect something is wrong. \n" ); document.write( " |
