Note 30 — Chapter XII
Reading edition
To find the number of square feet in the cleats, first find the number of "running" feet, that is, the total length of the cleats if they were stretched out in a long line, like one of the rails of a railroad track. Then, as the cleats are 3" wide (or one fourth of a foot), it will take four running feet to make one square foot. Therefore divide the number of running feet by four and the quotient will be the number of square feet.
