<PRE><B>Question 95994</B>
p=perimeter l=length w=width h=height
p(top or bottom)=2(l+w)=2(54+45)=198
p(1 of 4 sides)=2(h+l)=2(28+54)=164
So 2(198)+4(164)=perimeter of the entire box
396+656=1052 cm of paper
no.2 is similar to no.1. You should be able to do that now. 
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
{{{x/459.9=330/15}}}
multiply 459.90 times both sides.{{{x=330*459.90/15}}}=10,117.80 pesos
