(1) Find the number of cubic feet in the bin.
(2) Divide the number of cubic feet by 11⁄4.
(3) The result is the number of bushels.
Example: How many bushels will a bin hold, if its inside measurements are, length 20 feet, width 12 feet, depth 8 feet?
Solution: The number of cubic feet in a bin is 8 × 12 × 20, or 1920.
If 1 bushel contains 11⁄4 cubic feet, in 1920 cubic feet there are as many bushels as 11⁄4 is contained times in 1920, or 1536.
Work:
8 × 12 × 20 = 1920
1920 ÷ 11⁄4 = 1536.
