To calculate the volume of concrete needed, first convert the thickness from inches to feet: 4 inches is 1/3 of a foot. The volume in cubic feet is then calculated as 20 ft x 12 ft x (1/3 ft) = 80 cubic feet. Since there are 27 cubic feet in a cubic yard, divide 80 by 27 to find the volume in cubic yards: 80 / 27 ≈ 2.96 cubic yards. Therefore, approximately 3 cubic yards of concrete would be needed.

What area will 1 ton of crushed concrete cover?
It depends on the thickness and the density. One ton should be about 15 cubic feet when compacted, so it would cover 30 square feet 6 inches thick or 45 square feet 4 inches thick or 60 square feet 3 inches thick. It would make a driveway four inches thick, 9 feet wide and 5 feet long or a footpath 3 inches thick, three feet wide and 20 feet long.
