statement 1

M can be 111 or 999 so:

100*100*100 = 10*10*10*10*10*10 = 10^6 --> six digits number

1000*1000*1000 = 10*10*10*10*10*10*10*10*10 = 10^9 ---> eight digits number

insufficient

statement 1

10000 or 99999

10,000 = 100*100

100,000 = sqrt(100,000)*sqrt(100,000)

so either 100^3 or sqrt(100,000)^3

insufficient

the answer is (E)
