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( "\"x%2F459.9=330%2F15\"
\n" ); document.write( "multiply 459.90 times both sides.\"x=330%2A459.90%2F15\"=10,117.80 pesos
