1 x 10^{-5} = .00001
1 x 10^{-4} = .0001

Now find out how many times the size of a cell has to be multiplied to equal the diameter of a grain of sand. 

.00001 x 10 = .0001
.0001 = 1 x 10^{-5}

So the diameter of a grain of sand is 10 times longer than the diameter of the average cell in the human body.
