| Calculating
the volume of concrete: use inches for all dimensions |
Cubic yards in a rectangular pad =
|
length x width x thickness
46,656 |
| Cubic yards in a cylinder = |
diameter
x diameter x .785 x height |
| Weight of concrete = |
cubic yards x 3,900 lbs or cubic feet x 144
lbs |
| Volume Conversions: |
Cubic yards x 27 = cubic feet
Cubic yards x 46,656 = cubic inches
