Denominate Numbers-Capacity.

348. The standard unit of capacity used in measuring grain, fruits, vegetables, lime, coal, etc., is a bushel. A bushel equals 2150.4 cubic inches.

Note.-In measuring large fruits, vegetables, lime, and coal, the unit is the “heaped bushel." A heaped bushel equals about 14 stricken bushels.

DRY MEASURE.

2 pints (pt.) = 1 quart (qt.).
8 quarts

1 peck (pk.).
4 pecks

= 1 bushel (bu.). A bushel is nearly 11 cubic feet.

A “heaped bushel” is about 1} cubic feet. A "dry gallon” (4 quarts dry measure) equals 268.8 cubic inches.

Enough “ear corn” to make, when shelled, one bushel, occupies about 24 cubic feet. If the corn is inferior in quality it will occupy niore space than this—sometimes 2cubic feet.

PROBLEMS.

1. Find the capacity in bushels of a wheat bin 8 ft. by 8 ft. by 10 ft. *

2. Give the dimensions of the smallest bin in which 1000 bushels of oats may be stored.

3. In a bin 12 feet square, there is rye to the depth of 77 feet. How many bushels ?

4. How many bushels of potatoes (without heaping the bin) may be stored in a bin that is 8 ft. by 4 ft. by 6 ft.?

5. If the corn is of excellent quality, how many bushels of “ shelled corn may be expected from a crib of ear corn, 8 ft. by 10 ft. by 80 ft. ?

* for many practical purposes the approximate ratio (11) of the bushel to the cubic foot will give in such problems as these, results sufficiently accurate.
