On a Sunday afternoon, John and Melissa are strolling through downtown Knoxville. They notice World's Largest Rubik's Cube. A plaque points out there are about 4.3 * 10^19 different configurations for standard Rubik's Cube.
Assume 1000 different configurations can be tried for each hour. How many hours would it take to try all the possible conbination of the rubik's cube.
