Originally, a boxed toy from Amazon was provided in a box with dimensions  of 10cm by 4cm by 17cm. They also provided just enough special wrapping paper to cover (wrap) the box provided. However, the package was damaged during delivery process. Luckily, we have 4 other boxes that would fit the toy, but we still want to use the wrapping paper provided. Which box should I use to make sure I have enough wrapping paper to cover it?

The surface area is the sum of all the areas of the sides.


the origal box has  sides 10cm, 4cm, and 17cm

so the sides are 

10*4=40cm^2                front

10*4=40cm^2                back

10*17=170cm^2             top

10*17=170cm^2             bottom

4*17=68cm^2                side

4*17=68cm^2                side


40+40+170+170+68+68 = 556 cm^2    This is how much wrapping paper that you have,


NOW you have 4 options. Work out the surface area for each one, just like i did for the first one and see which ones you have enough wrapping paper for.
