CUBIC OR SOLID MEASURE.

ART. 94. Cubic or Solid Measure is used in measuring such bodies or things as have length, breadth, and thickness; as timber, stone, &c.

NOTE 1.-A pile of wood 8ft. in length, 4ft. in breadth, and 4ft. in

height, contains a cord.

50% cubic or

Also, one ton of timber, as usually surveyed, contains 50; solid feet.

QUESTIONS. How do you divide by 272? Of what denomination is the remainder? How is the true remainder found?-Art. 94. For what is cubic measure used? Recite the table. What are the dimensions of a pile of wood containing 1 cord? How many solid feet does a ton of timber contain, as usually surveyed?

NOTE 2.-A cube is a solid bounded by six square and equal sides.

If the cube is 1 foot long, 1 foot wide, and 1 foot high, it is called a cubic or solid foot. If the cube is 3 feet long, 3 feet wide, and 3 feet thick, it is called a cubic or solid yard.

Now, since each side of a cubic yard, as represented in the diagram, contains 9 sq. ft. of surface (Art. 93), it is plain, if a block be cut off from one side, one foot thick, it can be divided into 9 solid blocks, with sides 1 foot in length, breadth, and thickness, and therefore will contain 9 solid feet; and since the whole block or cube is three feet thick, it must contain 3 times 9 27 feet; for 3ft. X 3ft. X

=

To find the contents of a cubic or solid body, multiply its length, breadth, and thickness together.

WINE OR LIQUID MEASURE.

- ART. 95. Wine or Liquid Measure is used in measuring all kinds of liquids, except, in some places, beer, ale, porter, and milk.

NOTE 1.- By laws of Massachusetts, 32 gallons make 1 barrel. In some states 31 gallons, and in others from 28 to 32 gallons, make 1 barrel. 42 gallons make 1 tierce, and 2 tierces, 1 puncheon.

NOTE 2.-The term hogshead is often applied to any large cask that may contain from 50 to 120 gallons, or more.

NOTE 3.The Standard Unit of Liquid Measure adopted by the government of the United States is the Winchester Wine Gallon, which contains 231 cubic inches. It has the name Winchester, from its standard having been formerly kept at Winchester, England. The Imperial Gallon, now adopted in Great Britain, contains 277274 cubic inches; so that 6 Winchester gallons make about 5 Imperial gallons.

QUESTIONS. Art. 95. For what is wine or liquid measure used? Repeat the table. How many gallons make a barrel? How many a tierce? How many a puncheon? How is the term hogshead often applied? What is the standard unit of liquid measure?
