Then, multiply length times width. For triangular and circular areas, the square footage calculation is typically more complicated. To figure the area of a circle, multiply 3.14 (pi) times the square of the radius (the distance from the center of the circle to the circle's outside edge or circumference).How many feet are in a cubic foot?
In metric terms a cubic foot is a cube with sides 0.3048 metres in length. One cubic foot is the equivalent to approximately 0.02831685 cubic metres, or 28.3169 litres.
