664 sq ft. 12x13=166 x it by 4 walls=664 sq ft
Square footage estimates on drywall are based on the square footage of wall and ceiling that need to be covered.
156 square feet. (just multiply the two)
The square footage of an apartment will usually include bathroom space. When room size is used, closets are not included. When apartment size is figured, the perimeter is measured and these could be included.
The area of 15 feet times 15 feet = 225 square feet.
When you say "square footage", that usually means the area of the floor, and yes, you get that by multiplying (length of the room) x (width of the room). That tells you how much carpet you need for the floor. The walls and the ceiling also have their own "square footage". You have to know that to do things like paint and wallpaper. The ceiling has the same area as the floor. But for the walls, you have to do another whole different calculation. The easy formula for square footage of the walls is circumference (the distance around the room at the floor level) X the height of the wall (at the tallest point if the walls are uneven or have a peak). If the walls have a large number of windows, doors or other areas not to be painted, you may want to figure the rough square footage of these (estimate low, better to have a bit too much paint than a bit too little) and subtract that from your total. If you are estimating square footage for paint remember you may want to do two coats. If you are estimating for wallpaper, be sure to allow for the "pattern repeat".
A room that is 12 feet by 13 feet is 156 square feet in area
Square footage requires two measures of a rectangular room. There is only one measure given.
156ft squared
330 square feet
1400
156 square feet.
To calculate square footage, you multiply the length by the width of the room. So, if the room measures 10 ft. by 18 ft., your total area is 180 sq. ft.
