To make 8 inch tall column approximately 61 coins required. 
Given,
Total one cent coins stacked on top of each other in a column = 50
Height of column = 378 inches
Approximate height of one coin = ( 50 / 378) 
                                                     = 0.132 inches
To make an 8 inches tall stack No of coins required will be:
Number of coins required  = ( total height / height of one coin )
                    = ( 8 / 0.132 )
                    = 60.60
                     ≅ 61 coins
To make 8 inch tall column approximately 61 coins required.
