3,456. This is the answer although you can't really mix measurements and so this procedure involves converting the inches to cubic inches; as you can't really do the sum with standard inches and cubic feet (to the best of my knowledge anyway).

There are two ways you can work this out, either by using a conversion chart; which is most definitely the most straight forward way as it gives you the straight forward answer with no working out or, by using a fairly straight forward sum to work out the answer.

For the first method, there are many websites online with conversion charts here is a link to just one of these sites; www.asknumbers.com/CubicFeetToCubicInch.aspx In terms of working the answer out using a sum, you would need to do the following. One cubic foot is the equivalent of 12 cubic inches. So basically all you need to do is work out what 12 cubed is (which will give you one cubic foot) and then times this by two (to give you two cubic feet).

So, it would look like this:

12 X 12 = 144 X 12 = 1728 (this is the answer for one cubic foot)

1728 X 2 = 3456 (this gives you the answer for two cubic feet)

Converting any cubic inches into cubic feet can be done using this same theory; however I have never come across a sum which allows you to combine standard inches with cubed feet so hopefully this will help.
