Cubic foot factor method

Along with the square foot factor method, this is the most widely used method for estimating comparable building costs. The cubic foot factor method requires the computation of the cubic contents of a building by multiplying the building area from the outside of the exterior walls times the height of the building. This is used by appraisers to estimate the reproduction costs of a building, For example, if the average cubic foot cost of a certain building type is $20, and the total cubic  contents of the building are 5000 cubic feet, then the estimated reproduction cost of the building is $20*5000= $100,000.
