Using Laths to Work Up a Lather
At 40¢ a bunch for laths, 5¢ a sq. yd. for labor, and 8¢ a pound for nails, allowing a half-pound to a bunch, what will it cost to lath a hall 124 ft. long, 60 ft. wide, and 50 ft. high?
What would be the difference in the cost of the laths if they crossed each other?
