Measure the length plus the width, double that number. Take that number and multiply it by the height of the base board. That will give you the number of square inches of base. Divide the number of square inches by 144 and that will give you the square feet. There are 144 square inches in each square foot.
You can find the square footage of any shape, including a dome, by taking a few measurements in relation to its base. The base of any dome is typically a circle, and because of this, the measurement you must take to find the square footage is the radius.
Rectangle is length times width and triangles are base times height divided by 2.
Length x width = square footage
Area of a triangle = 1/2*base*height measured in square units
In order to calculate the square footage you need to find the length and the width of the room in feet. You multiply the length and the width to give you the square footage of the room
You can't, a hole has volume and thefore needs to be measured in cubic footage. Square footage is a measure of area not volume.
To find the square footage you should multiply the length and width of each room, and add up the results to give you the total square feet.
length x width
Area in square feet = pi*radius2
You measure its length and with and multiply the two. However, this will take no account of the height: the square footage in which you can stand, crawl or slide.
Find the measurements from one corner along the wall to the next corner and then repeat with the wall next to it. Once you've found the measurements, multiply them together to find the square footage.
Measure the length and height of thesign using a foot measure. Then multiply the lenght by the height and this will give you the square footage of the sign.
