50 MEASURE LOADS OF WOOD.

RULE. . Multiply the length by the breadth, and the product by the depth or height, which will give the content in solid feet; of which 64 make half a cord, and 198 a cord.

EXAMPLE. How many solid feet are contained in a load of wood, 7 feet 6 inches long, 4 feet 2 inches side, and 2 feet si inches high?

7 ft. 6 in.=7,5 and 4 ft. 2 in.=4,167 and 2 ft. S in= 2,25; then, 7,5 X4,167=31,2525X2,25=70,318125 solid feet, Ans.

But loads of wood are commonly estimated by the foot, allowing the load to be 8 feet long, 4 feet wide, and then 2 feet high will make half a cord, which is called 4 feet of wood; but if the breadth of the load be less than 4 feet, its height must be increased so as to make half a cor, which is still called 4 feet of wood.

By measuring the breadth and heighth of the load, the content may be found by the following

RULE.
Multiply the breadth by the height, and half the pro-
duct will be the content in feet and inches.

EXAMPLE.
Required the content of a load of wood which is 3 feet
9 inches wide and 2 feet 6 inches high.
