314 ARITHMETIC 



BINS, CISTERNS, ETC. 



It is frequently necessary to estimate the capacity of & 

 bin, box, or vessel in bushels, barrels, or gallons. The 

 volume of the bin or vessel in cubic feet or cubic 

 inches is divided by the number of cubic feet or cubic 

 inches in a bushel, barrel, or gallon, as the case may be. 

 For convenience of reference, the following table of 

 capacities is given: 



DRY MEASURE 



1 heaped bushel =2,747.71 cu. in. = 1.59 cu. ft., nearly 

 1 stricken bushel = 2, 150.42 cu. in. = 1.25 cu. ft., nearly 

 1 peck = 537.6 cu. in. 



1 quart = 67.2 cu. in. 



1 pint = 33.6 cu. in. 



LIQUID MEASURE 

 1 hogshead = 8.422 cu. ft. "] 

 1 barrel =4.211 cu. ft. 

 1 gallon =231 cu. in. 

 quart = 57.75 cu. in. 

 1 pint =28.875 cu. in. 



Rule. To find the capacity of a bin or other vessel in dry 

 measure or in liquid measure, divide the volume of the bin or 

 vessel in cubic inches by the number of cubic inches in the unit 

 of measure. 



The following table of approximate capacities is very 

 convenient in rough calculations: 



1 cubic foot = .63 heaped bushel 

 1 cubic foot = .80 stricken bushel 

 1 cubic foot = 7.50 liquid gallons 

 1 cubic foot = |# barrel 



The following short rules are approximate, but thei 

 results are sufficiently accurate for all practical purposes. I 

 Rule. To find the capacity of a bin in heaped bushels, multiply^ 

 the volume in cubic feet by .63. 



Rule. To find the capacity of a bin in stricken bushels, multiply^ 

 the volume in cubic feet by .8. 



Rule. To find the number of gallons in a cistern or other 

 vessel, multiply the volume in cubic feet by 7.5.
