Each dimension of him is reduced to 10% - this is one way of looking at it. In that case, the height becomes 0.21 m
But if the volume of the model is 10% of the human being, more complications arise. We need to approximate Jerry to a cyclinder of some dimensions and then work out the dimensions to give a cylinder of 10% of that maintaining the proportions.

All we have to do is find out what ten percent of 2.1 is and that will be our answer.
Thus.....10% of 2.1 = (10 x 2.1)/100 = 0.21
So our answer is 0.21 m

The scale model will be 10% of 2.1 m,
=2.1 x 0.1
=0.21m

2.1m = 210cm
210 * 10% = 21cm
Therefore, it would be 21cm tall
