EXERCISE 17. To MEASURE CORN IN CRIBS 



When the crib is equilateral: Multiply the length by the breadth, and that 

 again by the height, all expressed in inches, and divide the product by 2748 

 (the number of cubic inches in a heaped bushel); the quotient will be the 

 number of bushels of ears. Two-thirds of the quotient will represent the 

 number of bushels of shelled corn. 



Example: Find the number of bushels of shelled corn contained in a crib 

 12 feet long by 6 feet wide and 8 feet high, filled with ear corn. 



When the crib is flared at the sides: Multiply half the sum of the top and 

 bottom width by the perpendicular height, all expressed in inches, and that 

 again by the length in inches, and divide the product by 2748; the quotient 

 will be the number of heaped bushels of ears. Two-thirds of the quotient 

 will represent the number of bushels of shelled corn.
