How many square feet of paper do you need to cover a cube with a side 10 in. long? round your answer to two decimal places

Yes, this is the correct method. 10 in * (1 ft / 12 in) = 0.8333 ft, and the surface area of a cube is 6*s^2, where s is the edge length. Using s = 0.8333 in, I got a surface area of 4.17. If I used s = 0.833, I actually got 4.16, which is less accurate, so make sure you don't round too much when you do your calculations. XD 

But I hope this helps!

Well an average of 364, but possibly 252 if you are especially eager.
