dimensions of estimating:
 Linear Measure |  Square Measure |  Cubic Measure |
| 12 inches = 1 lineal ft. | 12" x 12" = 144sq" = 1sq ft. | 12" x 12" x 12" = 1728 cu" = 1 cubic ft. |
| 3 lineal feet = 1 yard. | 3' x 3' = 9sq feet = 1sq yd. | 3' x 3' x 3' = 27 cu feet = 1 cubic yard. |
| 5,280 lin ft = 1 mile. | 43,560sq' = 1 acre. | 36" x 36" x 36" = 46,656 cu" = 1 cubic yard. |
| Inches x .0833 = ft. Inches / 12 = ft. |
Sq" x .00694 = sq ft.
| Cu" x .0005787 = cu'. |
| Inches x .2778 = yds. | Sq" x .007716 = sq yds. | Cu' x .0002143 = cu yds. |
| Feet x .3333 = yds. | Sq' x .11111 = sq yds. | Cu' x .03704 = cu yds. |
| 100sq feet = 1 square (measure used in roofing). |
Useful Mathematical Formulas:
1. One of the most useful formulas is the Pythagorean theorem. The theorem states that the square of the hypotenuse of a right (90 degree angle) triangle is equal to the sum of the squares of its legs.
For Example: (3' x 3' = 9') + (4' x 4' =16') = 25', √25=5

This can be used for a wide variety of uses from squaring up a concrete form for a foundation, to attaching a new addition squarely to an existing building, or measuring a countertop -anywhere you must be certain of a right angle. Just plug in your numbers and get a calculator that has a square root function.
