The same way you calculate the surface area of any other rectangle: Multiply the length of the wall by its height.
thicknesss of wall multiply by height of wall multiply by length of wall and multiply by density of wall (19000)
measure each wall length in feet. for example a square has 4 sides and say each wall measures 4 ft. Multiplylength by width and that would be 16 sq feet(hopefully nothing that small). What are your mesurements?
Multiply the length of one wall by the height to give you the square footage of that one wall. Then repeat for all other walls in the room and add up the total.
Wouldn't that be 6 times 11.5 times 8 = 552 cubic feet. You need to measure the length and width of the room. Using a retractable measuring tape, or laser measuring tool, measure the room from end to end in one direction, an d in the other. Draw a rectangle on the paper and record the measurement of each wall on the paper. If your room is rectangle, then you are done. If your room is odd shaped, you will also need to measure odd corners and walls.
Area.

You normally measure the linear dimensions and then calculate the area (square footage).If you have a rectangular room, you measure its length and width in feet and then multiply the two numbers to get the area of the room in square feet. If the room is not rectangular (eg with a bay, an alcove or an L-shaped room) you will need to divide it up into simpler shapes, calculate the area of each shape and add the areas together.

A tape measure is typically used to measure the length of a room. Simply extend the tape along one wall to the opposite wall to get an accurate measurement.

The area of square is : 1.0
As you state circumference, it may be assumed the room is circular/round. If so the answer is 3.141 multiplied by the diameter. If the room is square/oblong, measure each wall with a tape and add the four measurements together
Multiply the length of each wall by the height of each wall and that will give you the area of the walls. Combine the resulting numbers for each wall and you have the area in square feet.
Every wall needs two measurements ... the length of the wall and the height of the wall.In a typical room, the walls all have the same height, but their lengths may be different.The area of each wall is (length) multiplied by (height).After you "do" the area of each individual wall, you can add up the four numbers.The sum tells you how much paint or wall-paper you'll need to cover the walls.
