Question from aLAN, a parent: How many CF of concrete does it take to pour a 1000 SF area with concrete at 4" thick? |
Hi,
The base is 1000 square feet and the thickness is uniform so the volume is the area of the base times the thickness. you want the volume in cubic feet so you need to convert the thickness measurement to feet. One foot is 12 inches so 4 inches is 4/12 - 1/3 feet. Hence the volume is 1000 × 1/3 = 333.33 cubic feet.
You can check your answer with our volume calculator.
