The maximum amount of money Jamar should spend on the board is $ 340 for 20 feet board and the minimum is $ 68 for 4 feet of board.
To calculate the maximum and minimum table distance that Jamar needs, we must take into account that a triangle must have 3 angles that add up to 180°. According to this, we can distribute the angles in such a way that the distance to join the two boards that Jamar has is the smallest and the largest.
For example the largest possible angle opening might be 179.8 ° and the smallest would be 0.1 °.
Based on this information, we can conclude that the longest board that Jamar may require to build the box is 20 ft, and its value would be $ 340.
On the other hand, the smallest board Jamar could require is 4 ft, and its price would be $ 68.
