An ant lives on the surface of a cube with edges of length 7cm. It is currently
located on an edge x cm which is 2cm 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 which is also equal to 2 cm from one
of its ends)
(i) What is the length of the shortest route to the grain if x = 2cm? How many routes of
this length are there?javascript:void(0)
(ii) Find an x for which there are four distinct shortest length routes to the grain.
