An ant lives on the surface of a cube with edges of length 7cm. It is currently located on an edge x cm from one of its ends. While traveling on the surface of the cube, it has to reach the grain located on the opposite edge (also at a distance xcm from one of its ends) as shown below. (i) What is the length of the shortest route to the grain if x = 2cm? How many routes of this length are there? (ii) Find an x for which there are four distinct shortest length routes to the grain
Please see attach image for figure. Please tell me the steps you have followed to arrive at the solution.
