A lizard is present on one corner of cube, It wants to reach diagonally opposite corner of cube. You have to calculate minimum distance lizard has to cover to reach its destination.
Note : Lizard can’t fly, it moves along the wall.
You are given a representing side of cube.you have to calculate minimum distance lizard has to travel.
Input : 5 Output :11.1803 Input :2 Output :4.47214
As we have to calculate the minimum distance from one corner to another diagonally opposite corner. if lizard able to fly then the shortest distance will be length of diagonal. But it can’t.
So, to calculate minimum distance, just open the cube, as describe in diagram.
Let us suppose, lizard is initially at point E.and it has to reach at point A(as A is diagonally opposite to E).Now we have to find AE.
Just use Pythagoras theorem, As
