A typical 3-D printer creates objects by laying down layers of ink one on top of another. The average thickness of a layer depends on the caliber of the printer. For one particular 3-D printer, the average thickness of a layer is 102 µm (micrometers). When creating a 1-inch cube, the printer takes 6 seconds to lay down each layer of ink. Approximatley how long should it take this printer to create a 1-inch cube? (There are 1,000,000 micrometers in a meter, and 1 inch is approximatley equal to 0.0254 meters.)
a) 12 minutes
b) 25 minutes
c) 40 minutes
d) 1 hour, 6 minutes
