I measured the blocks with a dial caliper to get the most accurate results. I did this to check if each cube that I measured was within the constraints for the cube size. I measured from grain to grain on the cubes.
Acceptable range is the minimum and maximum length of each cube. and anything outside of the acceptable range must be replaced. To find the acceptable rang/ Standard deviation of the cubes, I found the mean by adding the measurements together and dividing by the amount of inputs I had. I then used the Excel program to calculate the standard deviation using the data that I gathered.

The degrees of freedom are the directions that a 3 dimensional shape can move on the X, Y, and Z plane. up and down, left right, and rotating around those axes. I had to restrict all the degrees of freedom for my shape so that it would not move at all.

Present the solution
I believe that my cube meets all the criteria except being at a efficient difficulty for a 3 year old. My Inventor experience was very good. I thought i had a good handle on the program while i was using it. making the cube parts and assembling them was pretty easy and the software helped with that a lot. Through my design process i created a cube with spare wood cubes, tested and retested it, and now i finally present it. this particular project did not require a decision matrix because I only had one cube idea. I would change the difficulty level of my cube if I had to, in order to be sufficiently difficult for a three year old.
