multiplied by the number of days during which they have to 

 be fed, the result will equal the number of cubic feet of silage 

 space required. Supposing thirty animals have to be fed for 

 six months, or 184 days, the total amount of space required 

 would be 30 x 184 = 5,520 cubic feet. 



To find the number of cubic feet in a square or rectangular 

 silo multiply the length in feet by the width, and then by the 

 height, and the result will give the total number of cubic feet. 

 Thus, if a square silo measures [4 feet each way on plan and 

 25 feet in height, the cubical contents would be 14 feet x 14 

 feet x 25 feet = 4,900 feet. 



In the case of a round silo, multiply the square of the 

 diameter in feet by the height, and then by 7854. For 

 example, if a round silo measures 14 feet in diameter and 

 25 feet in height, the cubical contents would be 14 feet x 14 

 feet x 25 feet x 7854 = 3,848 feet approximately. 



The following table (No. CXXXII) shows the capacity 

 of silos of different dimensions and the acreage of maize re- 

 quired to fill them, on the basis of a crop of I 5 tons (Colonial)

747. Position. — As regards position, the silo should be 

 placed as near as possible to the centre of feeding, to minimize 

 the labour of carrying food to the various mangers. In round 

 or octagonal farm buildings, such as are common in America,
