Answer 2

just multiple each side

Answer 3

Well, the surface area of the box would be the sum of the surface areas of each side.

Answer 4

So draw a diagram of the box, and figure out what the length/widths are for each of the sides, then add them all up.

Answer 5

or rather add the areas which you get by taking the products of the length/widths.

Answer 6

I am trying to teach this to my high school homeschooler and haven't done this stuff for 30 years, if you show me the calculation, I can use a different size rectangle and have him do the work.

Answer 7

Did you draw a picture?

Answer 8

Plugging in the numbers isn't the 'work' part of the problem. Figuring out the equation is.

Answer 9

So you'll need to be able to explain why you're using the equation you're using.

Answer 10

yes, I have the picture drawn, guess I need to know the equation, thanks for your help

Answer 11

Ok, so look at the picture.. It should look like this.. So you can see that you have two sides where the dimension of the side is length x width. And you have two sides where the dimension is width x height and two sides where the dimension is length x height. So find each of those areas, then add them up.
