How much carpet would a person need to buy for a rectangular room that has dimensions of 10 yards by 18 feet?
The answer would be 60. :)
Rhonda carpeted her 12ft by 8ft living room How many square feet of carpet did she buy?
96 square feet. To calculate square feet simply multiply length by width - the result is the area in square feet.
What are the applications of surface area?
It depends what you need to do to or with the area. You need it to make a purchase i.e. land or carpeting. You may need it to quantify how much paint to buy for painting a room or fertilizer for your yard. It can be used in Physics, i.e. a pound of steel shaped into a solid ball will sink, yet if shaped into a large bowl, it floats. Just too many applications to list.
How many square feet are in a room which is 4 ft buy 10 ft?
The floor and the ceiling are each (4 x 10) = 40 square feet. In order to calculate the area of the walls, we would have to know the height of the ceiling.
How do you calculate how much carpeting is needed for a room?
The obvious answer is to figure out the total area of the room and then buy an area of carpet equal to this amount. Since rooms often do not match up with standard carpet widths, this can lead to a patchwork of small bits cobbled together to cover the last areas of the room. Choose an area of the room that can be covered with one piece of the carpet. This is carpet area #1. Then determine the fewest large pieces of carpet needed to cover the rest -- even if there is some waste involved. This is carpet area #2. Total carpet purchase is area 1+2.
