What is the shortest distance an ant can walk from one vertex of a cube, whose side length is 1cm, to the opposite vertex?
Sqrt(2) cm=would be the shortest distance.
Walking through two adjacent sides of a cube to get to the opposite vertex of the cube:
x2 = 12 + 22 ---> x2 = 1 + 4 ---> x2 = 5 ---> x = sqrt( 5 )
