Want this question answered?
There is no way to answer that without knowing how deep the concrete will be.
475
891 (square meters) = 0.22 acres.
The answer depends on how deep you want the asphalt layer to be!
Cubic means a three-dimensional volume. Square means a two-dimensional flat area. The area that can be covered by a cubic yard of rock will depend on how deep the rock bed will be.
It depends upon how deep the cement will be.
depends how deep
well do to my calculations i made is that it is 6 or 18 feet long
It depends on how deep it is. If it is 6 inches deep, you will need 77 yards.
The answer will depend on how deep the cement needs to be.
16 bags for every 3 inches deep
Given only the information that appears in the question you cannot. You also need to know how thick (deep) the cement needs to be.
4.4 bags for each 1-foot deep. 2.2 bags for each 6-inches deep. Each 5-ft3 bag will cover the area to 2.72 inches deep.
9.72 Cubic Yards of Concrete is required, if you are going to order by cement truck. 874.8 bags of 40# (40 lbs) bags, or 583.2 bags of 60# 437.4 bags of 80#
You will need a minimum of 0.665 cubic meters of cement for this walkway. (if 60 lbs per bag, it is 52.1 bags. If 80 lbs per bag, it is 39 bags).
You would need 31, 80 pound bags to cover 1 cubic yard at 4 inches deep. If you would like the depth to be 6 inches, 45 bags would be needed.
