483. To find the exact capacity of a bin in bushels. Eule. — Divide the contents in cubic inches by 2150.42,

the quotient will represent the number of bushels.

484. To find the cubic contents in a given number of bushels.

Eule. —1. Multiply the number of bushels by 2150.42 ;

the product will be the number of cubic inches, which may

be reduced to higher denominations if required.

Since a standard bushel contains 2150.42 cu. in., and a cubic foot contains 1728 cu. in., e, bu. is to a cu. ft. nearly as 5 to 4; or a bu. is equal to 1\ cu. ft., nearly. Hence for all practical purposes,

2. Any number of cubic feet diminished by % will represent an equivalent number of bushels.

Thus, 250 cu. ft.— £ of 250 cu. ft., or 50 cu. ft = 200, the number of bushels in 250 cu. ft.

3. Any number of bushels increased by \, will represent

an equivalent number of cubic feet.

Thus, 200 bu. + | of 200 bu., or 50 bu.=250, the number of cubic feet in 200 bushels.

WRITTEN EXERCISES.

485. 1. A bin is 6 ft. long, 5 ft. wide, and 4 ft. deep. How many bushels will it hold ?

2. A rectangular box will hold 128 bu. What is its volume in cubic feet ?

3. How many bushels of wheat can be put in a bin 8 ft. long, 6 ft. 6 in. wide, and 3 ft. 4 in. deep ?

4. What must be the depth of a bin to contain 240 bu., its length being 10 ft. and its width 5 ft. ?

Operation.— 240 bu. + 60 bu.=300; 300-^10x5=6 ft., the depth. Eule. — Divide the contents in cubic feet or inches by the product of the two dimensions, in the same denomination.
