3. Shown below are two subjects that have the same attenuateon profiles from both left to right and top to bottom. This is accomplished by changing the material in squares i, j, k, m, n so that they might have different attenuateon coefficients than the original material. The original material (subject B and the top and bottom portions of subject C) has attenuateon coefficient 0.5 cm . If the attenuateon coefficient of material i is 0.2 cm , find the attenuateon coefficient values for the remaining squares j, k, m, n. k m n H C
