Andy’s How To: Plan 4100
http://www.andyshowto.com/4100.htm
- Scroll down to the plans for the first and second floors of the house.
- Refer to the room dimensions to calculate area, perimeter and volume.
- You may want to sketch the rooms on grid paper to help you solve problems.
Use the floor plan of the house to answer the questions below. Show your work.
- If the owner of this home wanted to put a wallpaper border all around the top of the walls in the game room, how long of a border would she need? If the border is sold by the yard, how many yards will she need to buy?
- The homeowner buys a large circular rug for the floor of the den. The rug measures 20 feet in diameter. What is the area of the rug?
- The homeowner wants to paint the walls of the living room and dining room the same color. If the ceilings are 9 feet high, and one gallon of paint covers 400 square feet, how many gallons of paint should she buy? (Ignore the door and window openings.)
- If the owner puts wall-to-wall carpeting in the living room, dining room, and master bedroom, how many square yards of carpet does she need to buy? Round to the nearest tenth of a square yard.
(Hint: 9 square feet = 1 square yard)
- If the owner wants to put a pool table measuring 6 feet by 12 feet lengthwise in the center of the game room, how much walking space would be left on each side of the table?
- How could you determine the area of the space in the game room not used by the 6 foot-by-12-foot pool table? Calculate the area of the unused space.
- The owner decides to tile the floors in the kitchen and eating areas. The tile she will use is sold in 12-inch-by-12-inch squares, at a cost of $1.50 per tile. How much will it cost her to buy all the tiles she will need?
- Each kitchen cabinet is 3 feet tall, 2 feet wide and 1.5 feet deep. Find the total volume of 4 cabinets.
Math at Home
Today I viewed a Web site with house floor plans. I calculated that a 16-foot-by-20-foot bedroom would need square feet of carpeting. I also discovered that to put up a wallpaper border you need to find the of the room.
You can find out more about this topic by asking your teacher or parents to show you other Web sites.
