Suppose your Unit 2 Project is a plan for renovating the family room in your home. To estimate the cost of new laminate flooring, you need to include an estimate of
- the total coverage area of the floor
- any possible waste (as a result of cuts)
The flooring will have to be cut to fit
- along the walls
- around a fireplace (if there is one)
- on and/or around stairs
- around furnace vents (if there are vents)
- any smaller areas of the room, such as a closet
Does your family room have any unusual features? How would you estimate the amount of flooring you would purchase?
