# Exercise: An ant lives on the surface of a cube with edges of length 7cm. It is currentlylocated 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 oneof its ends) as shown below.(i) What is the length of the shortest route to the grain if x = 2cm? How many routes ofthis length are there?(ii) Find an x for which there are four distinct shortest length routes to the grain.Scope and EffortTotal expected
