Chapter 3.3, Problem 2CE

Flooring and Carpeting Estimates of matched or tongue-and-groove (T&G) flooring—stock that has a tongue on one edge—must allow for the waste from milling. To allow for this waste, $\frac{1}{4}$ of the area to be covered must be added to the estimate when 1-in. by 4-in. flooring is used. If 1-in. by 6-in. flooring is used, $\frac{1}{6}$ of the area must be added to the estimate. (Hint: The floor is a rectangle. Area of a rectangle = length × width.)

1. a. A house has a floor size 28 ft long by 12 ft wide. How many square feet of 1-in. by 4-in. T&G flooring will be required to lay the floor?
2. b. A motel contains 12 units or rooms, and each room is 22 ft by 27 ft, or 594 sq ft. In five rooms the builder is going to use 4-in. stock and in the other seven rooms 6-in. stock—both being T&G. How many square feet of each size will be used?
