ESTIMATION OF CROPS IN THE BULK 

 CORN 



78. Approximately 3^ cu. ft. of corn in the husk and 

 2jcu. ft. on the cob make a bushel. 



There are 2150.4 cu. in. of shelled corn in a bushel. 



79. The capacity of a crib in bushels equals the product 

 of the length, width, and depth in feet divided by 3| for 

 corn in the husk, and by 2j for corn on the cob. 



80. Rule. To find the number of bushels of corn in the husk 

 in a round pile, square the distance across the pile in feet 

 and multiply by 3; then multiply by j the height of the p He 

 in feet and divide by 3^. 



EXERCISE 



1. How many bushels of corn in the husk are there in a 

 crib 12 ft. long, 8 ft. wide, and 7 ft. high ? 



2. How many bushels in the husk will a rail pen 7 ft. 

 long, 7^ ft. wide, and 9 ft. high hold ? 



3. Measure the crib at home and estimate how many 

 bushels it will hold. How many bushels are in it now ? 



4. Measure the wagon box at home and estimate the 

 number of bushels it will hold. 



5. How high must a crib 10ft. long and 8ft. wide be 

 built to hold 150 bu. ? 



6. How many bushels of corn in the husk are there in a 

 round pile 12 ft. across, tapering to a point 6 ft. high in the 

 middle ?
