Algebra.Com's Answer #345063 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! a rectangular box is to be constructed with its length four times the size of its width, and its height one half the size of its length. \n" ); document.write( " the volume of the box must be 1000 cubic centimeters. find the dimensions of the box \n" ); document.write( ": \n" ); document.write( "Let x = the width of the box \n" ); document.write( "then \n" ); document.write( "4x = the length of the box \n" ); document.write( "and \n" ); document.write( "2x = the height of the box (half the length \n" ); document.write( ": \n" ); document.write( "Volume: L*W*H \n" ); document.write( "therefore \n" ); document.write( "x*4x*2x = 1000 \n" ); document.write( "8x^3 = 1000 \n" ); document.write( "Find the cube root of both sides \n" ); document.write( "2x = 10 \n" ); document.write( "x = 5 cm is the width \n" ); document.write( "then \n" ); document.write( "4(5) = 20 cm is the length \n" ); document.write( "and \n" ); document.write( "2(5) = 10 cm = the height \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check this: 5 * 20 * 10 = 1000 \n" ); document.write( " |
