The mass of the up quark=.005 times its electrical charge of 2/3 =.003333333
The mass of the down quark=.01 times its electrical charge 0f -1/3=.003333333
The sqrt. of .003333333 is .057735026 , and .057735026^3 =.0001924
Dark matter^3 = .01924
It might be important to point out that the sqrt. of .005 = .070710678, * 2 = a perfect .141421, a very important constant.
And it just so happens that the sqrt. of the mass of the down quark .01 = .10, * 2 = .2
