Linear Feet is probably the simplest quantity to calculate. Lumber yards
sometimes sell lumber by the linear foot which makes it easy to calculate the
cost per piece.
Linear feet = number of items X the item length
Board Feet will add two other dimensions to calculating the cost of materials.
Lumber suppliers sometimes sell their lumber per thousand board feet. A board
foot is one linear foot of lumber - one foot wide - one inch thick. A 1 x 12
piece of pine which is 12 feet long will equal 12 board/feet. In the same way a
2 x 6 piece of pine 12 feet long will equal 12 board/feet.
Board feet = Linear feet X ((thickness inches X width inches) / 12 inches)
Square Feet is a simple process of multiplying the length X the width. You
will need to know how many square feet there is in the foundation in order to
estimate how much vapor barrier to buy and to determine how much the
termite pre-treat will cost.
Square Feet = Length X Width
Cubic Feet adds one other dimension to square feet. This dimension is depth.
Cubic Feet = Length X Width X depth
Cubic Yard = Total Cubic Feet / 27 cubic feet
