Iam a cube that has a length, width, and height of one unit

How do you.  I am a 200-pound male engineer.  I have never met a cube with uniform dimensions before, and I am pleased to make your acquaintance.

From the personal information you've given me, along with my background in Physics and Math, I've determined that you have twelve edges and six faces,  each of your edges is parallel to three others, and each of your faces is parallel to one other.  Your surface area is six square units, and your volume is one cubic unit.  

I don't know your weight.  But seeing you sitting there comfortably on the table, I know that your density is greater than 0.00128 g/mL (the density of air).  

And if you don't mind jumping into this bucket of water for just a moment, I'll be able to watch you and determine whether your density is more or less than 1 g/mL ... that's the density of water, so I'll only need to see whether you sink or float.  

answer: a ball

explanation: because it will bounce

come closer and become far apart and become steam/gas
