Fórmula
## How to Calculate Concrete Bags Needed ### Formula **Bags = Total Cubic Feet / Coverage per Bag** | Bag Size | Yield (cu ft) | |----------|---------------| | 80 lb | 0.60 cu ft | | 60 lb | 0.45 cu ft | | 40 lb | 0.30 cu ft | For small projects under 1 cubic yard, bagged concrete is more practical. For larger projects, order ready-mix from a concrete plant.
Ejemplo Resuelto
A 10 ft by 10 ft slab, 4 inches thick, using 80 lb bags.
- 01Depth in feet: 4 / 12 = 0.333 ft
- 02Volume = 10 × 10 × 0.333 = 33.33 cu ft
- 03Cubic yards = 33.33 / 27 = 1.23 cu yd
- 04Bags (80 lb) = 33.33 / 0.60 = 55.6 → 56 bags
Preguntas Frecuentes
How many 80 lb bags of concrete in a cubic yard?
There are 27 cubic feet in a cubic yard. Each 80 lb bag yields 0.60 cubic feet. So 27 / 0.60 = 45 bags per cubic yard.
Should I use bags or ready-mix concrete?
For projects under 1 cubic yard, bags are practical. Over 1-2 cubic yards, ready-mix delivered by truck is more cost-effective and produces better results.
How much water do I add to an 80 lb bag?
Approximately 3 quarts (about 6 pints) of water per 80 lb bag. Follow the manufacturer's instructions on the bag for best results.
