ANSWER:
Solution
Step 1 of 8
In this problem, there are four brick which are placed at the edge of each other at the edge of the table we have to find the maximum distance of the brick 1,2,3 and 4 which remains on each other, and we have to determine a general formula and also we have to calculate the minimum number of bricks.
