Algebra.Com's Answer #69932 by edjones(8007) You can put this solution on YOUR website! p=perimeter l=length w=width h=height \n" ); document.write( "p(top or bottom)=2(l+w)=2(54+45)=198 \n" ); document.write( "p(1 of 4 sides)=2(h+l)=2(28+54)=164 \n" ); document.write( "So 2(198)+4(164)=perimeter of the entire box \n" ); document.write( "396+656=1052 cm of paper \n" ); document.write( "no.2 is similar to no.1. You should be able to do that now. \n" ); document.write( "no.3 we set up a proportion with cost on the left side of the equal sign and area to be painted on the right \n" ); document.write( " \n" ); document.write( "multiply 459.90 times both sides. \n" ); document.write( "EdJones\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
