What is the distance from the Earth's center to a point outside the Earth where the gravitational acceleration due to the Earth is 1/12 of its value at the Earth's surface?

Have u hrd of the inverse square law of gravity?
Multiply the distance from the center by sqrt12 (=3.464) and what do u get?
If you want the answer in km, multiply sqrt12 by the Earth's radius
