How many pieces of 8-foot chair rail are needed for the dining room, installed at a height of 36 inches?

To determine the number of pieces of 8-foot chair rail needed for a dining room, it's important to first know the total perimeter of the room, as the chair rail will be installed at a consistent height of 36 inches around the walls.

Assuming the dimensions of the dining room are not provided in the question, let's think about the general approach.

1. Measurement of Chair Rail: Each piece of chair rail is 8 feet long. Convert this to inches to make calculations more straightforward—8 feet equals 96 inches.

2. Height of Installation: The provided height of the chair rail is 36 inches. This indicates that the installation is at a standard height, which will not impact how much material is needed; the focus is on the perimeter.

3. Calculate Total Length Required: If we assume the total perimeter of the dining room is provided (let's say it is 40 feet, for example), we'd convert that to inches (40 feet x 12 inches/foot = 480 inches).

4. Divide Total Length by Length of Each Piece: To find out how many 8-foot pieces are needed, divide the total length needed by the length of each piece. For instance, if
