Algebra.Com's Answer #14310 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! An open-top box is to be connected from a 6 by 8 foot rectangular cardboard by cutting out equal squares at each corner and then folding up the flaps. Let x denote the length of each side of the square to be cut out. Find the function V that represents the volume of the box in terms of x. \n" ); document.write( "This is what I got: \n" ); document.write( "6x+8x+x=14x² \n" ); document.write( "x=14 \n" ); document.write( "LENGTH OF BOARD=6 FT....WIDTH OF BOARD =8 FT. \n" ); document.write( "IF X LONG SQUARE PIECES ARE CUT AT 4 CORNERS WE SHALL HAVE THE BOX DIMENSIONS AS \n" ); document.write( "HEIGHT =X.....LENGTH = 6-2X.....WIDTH =8-2X \n" ); document.write( "VOLUME = V = L*W*H =X(6-2X)(8-2X)=X(48-28X+4X^2)=48X-28X^2+4X^3\r \n" ); document.write( "\n" ); document.write( "THE GRAPH WILL LOOK LIKE THIS \n" ); document.write( " \n" ); document.write( "FROM THE GRAPH YOU CAN SEE V HAS A PEAK AT X=ABOUT 3.5 FEET \n" ); document.write( " \n" ); document.write( " |
