A solid is an extension which has length, breadth, and thickness; as a box, a room, or a book. solids are measured are called cubic units. They are cord (cd.), cubic yard (cu. yd.), cubic foot (cu. ft.), and cubic inch (cu. in.). A pile of wood 8 feet long, 4 feet wide, and 4 feet high is a cord. One foot in length of this pile, or 16 cu. ft., is a cord foot. EXERCISES (Oral). 245. 1. How many cu. ft. in 2 cu. yd.? In 5 cu. yd.? In cu. yd.? In & cu. yd.? 2. How many cu. yd. in 81 cu. ft.?

Capacity signifies extent of room or capability of holding. Units of capacity are of two kinds : units of liquids and units of dry substances. 248. Liquid units are used for measuring all kinds of liquids. They are gallon (gal.), quart (qt.), pint (pt.), and gill (gi.). Relation of the Units. 4 gills = 1 pint, In measuring cisterns, etc.: 2 pt. = 1 quart, 4 qt. = 1 gallon. 31 gal. 1 barrel (bar. or bbl.). 63 gal. = 1 hogshead (hhd.). A gallon contains 231 cubic inches. The barrel and hogshead are not fixed quantities, but vary when used for commercial purposes. EXERCISES (Oral). 249. 1. How many gills in 2 pt.? In 5 pt.?

They are gallon (cong.), pint (O), fluid ounce (f3), fluid drachm (f3), and minim (TM). 251. Dry units are used for measuring quantities that are not liquid; such as grain, potatoes, etc. The units are bushel (bu.), peck (pk.), quart (qt.), and pint (pt.). Relation of the Units. 252..1.
