SOLID OR CUBIC MEASURE.

85. Solid or cubic measure is used in measuring stone, timber, earth, and such other things as have the three dimensions of length, breadth, and thickIts denominations are tons, cords, yards, feet, and inches.

when the sides of the cube are one yard, as in

3 feet=1 yard.

3 feet-1 yard.

the figure, the cube is called a cubic or solid yard. The base of the cube, which is the face on which it stands, contains 3x3 9 square feet. Therefore 9 cubes, of one foot each, can be placed on the base.

If the solid were one foot high it would contain 9 cubic feet; if it were 2 feet thick it would contain two tiers of cubes, or 18 cubic feet; and if it were 3 feet high, it would contain three tiers, or 27 cubic feet. Hence, the content of a solid is equal to the product of its length, breadth, and thickness. Therefore, 1 cubic foot contains 12 × 12 × 12=1728 cubic inches.
