Answer:
the equivalent units of production related to the material is 126,000 units 
Step-by-step explanation:
The computation of the equivalent units of production related to the material is shown below:
 = Completed units + Ending inventory units - Beginning inventory units. 
 = 65,000 units + 65,000 units - 4,000 units 
= 126,000 units
hence, the equivalent units of production related to the material is 126,000 units
