TO FIND THE AREA IN SQUARE FEET & VOLUME IN CUBIC FEET

Area of a rectangle or square | Length x Width
Area of a right triangle | Length x With divided by 2
Area of a circle | Radius squared x 3.1416
Volume | Area x Height

CONCRETE

A cubic foot = 1728 cubic inches. | A cubic foot weights approx. 150 lb.
A cubic yard = 27 cubic feet. | A cubic yard weights approx. 4050 lb.

TO CALCULATE CONCRETE

length in feet x width in feet x height in feet = cubic feet. Then dived by 27 to get number of yards required Note: to convert inches to a dismal divide the number of inches by 12 ( or use chart above )
