Sometimes, when you try to build any concrete structure as yourselves you need to make a plan. The most important part is to calculate a number of bags of concrete and all prices.
How Many Bags of Concrete is a Yard?
You need exactly to take 72 50lb bags, or 60 60lb bags, or 40 90lb bags to fill one cubic yard of concrete. If you use a 30kg bag, you will need 61 bags to fill one cubic concrete yard. To easy measure, remember that concrete weighs about 150lbs per cubic foot.
Table: How Many Bags of Dry Mix Concrete in a Yard:
| Bag Size | Bags/yard | Cubic Feet per bag | Bags per ft | 1 Thick Coverage/bag |
|---|---|---|---|---|
| 10lbs | 360 | 0.075ft | 13.33 | 0.9ft |
| 20lbs | 180 | 0.15ft | 6.67 | 1.8ft |
| 25lbs | 144 | 0.188ft | 4.35 | 2.26ft |
| 40lbs | 90 | 0.3ft | 3.33 | 3.6ft |
| 50lbs | 72 | 0.376ft | 2.7 | 4.44ft |
| 55lbs | 65.45 | 0.43ft | 2.33 | 5.16ft |
| 60lbs | 60 | 0.45ft | 2.22 | 5.4ft |
| 66lbs | 54.55 | 0.52ft | 1.92 | 6.24ft |
| 80lbs | 45 | 0.6ft | 1.67 | 7.2ft |
| 90lbs | 40 | 0.675ft | 1.48 | 8.1ft |
Suppose we talk about the density of the concrete and the yards that will be covered with this. Then having a hunk of concrete that weighs around 150lbs per cubic foot is not as dense as it seems because when we work to cover three-dimensional areas, there are higher chances that we would end up with large numbers in terms of volume. Take a small example to understand that the concrete quantity covering 27 cubics of feet will weigh around 4,056 pounds.
Some people get the idea of concrete bags since concrete bags usually come in the packaging of pounds. Sometimes it is being rounded up whenever the summed up amount is giving an incomplete figure of number. It is a usual practice that is being advised or recommended to people who buy some extra concrete rather than coming and buying again.
Another fun fact about this is that there is always a tiny amount present in the concrete bags than written on its label. Therefore, it can make and cover an additional area.
The reason behind it is that when we add water to the concrete, it spreads and adds up to a few extra pounds of weight to concrete that ends up covering additional feet of the area.
