Algebra.Com's Answer #149768 by tutorvolunteer(9) ![]() You can put this solution on YOUR website! To do this, you need the formula for volume of a rectangular prism.\r \n" ); document.write( "\n" ); document.write( "V of rect prism = length * width* height = (a-3)\r \n" ); document.write( "\n" ); document.write( "We know the length = (a-3)/(a-7) and the height, or depth = (a+b)/(a-7)\r \n" ); document.write( "\n" ); document.write( "Therefore we can solve for the width:\r \n" ); document.write( "\n" ); document.write( " a-3 = (a-3)/(a-7) * (a+b)/(a-7) * width\r \n" ); document.write( "\n" ); document.write( "That is the conceptual part of the problem. With a little algebra, you can solve for the width in terms of a. (You will not get an exact answer) \n" ); document.write( " |
