2,000 lb in 60 lb bags: 33 and a remainder
2,000 ÷ 60 is 33.3, so the load is 33 whole bags, 1,980 lb, with 20 lb unused. In 80 lb bags the same payload is 25 bags and comes to 2,000 lb.
33 bags of 60 lb mix make 14.85 cubic feet, 44.6 square feet of 4 inch slab. An 8 × 10 ft slab needs 60 bags, so it is 2 trips. With 400 lb of people and tools aboard, each trip drops to 26 bags.
Bags left after people and cargo
Payload is everything the truck carries: the driver, passengers, tools, a toolbox, a hitch and the bags. Take the rest off first.
| Already aboard | Payload left for bags | 40 lb bags | 60 lb bags | 80 lb bags |
|---|---|---|---|---|
| Nothing else aboard | 2,000 lb | 50 | 33 | 25 |
| 200 lb of people and cargo | 1,800 lb | 45 | 30 | 22 |
| 400 lb of people and cargo | 1,600 lb | 40 | 26 | 20 |
| 600 lb of people and cargo | 1,400 lb | 35 | 23 | 17 |
Use the payload on the sticker inside the driver's door of your own truck, not a figure for the model or the class. Bag weights are dry weights as sold.
Trips for a slab with 60 lb bags (2,000 lb payload)
Each row is a 4 inch slab with no waste added, at 33 bags a trip.
| Slab | Concrete | 60 lb bags | Trips | Weight of the slab |
|---|---|---|---|---|
| 8 × 8 ft | 21.3 ft³ | 48 | 2 | 3,200 lb |
| 8 × 10 ft | 26.7 ft³ | 60 | 2 | 4,000 lb |
| 10 × 10 ft | 33.3 ft³ | 75 | 3 | 5,000 lb |
| 10 × 12 ft | 40.0 ft³ | 89 | 3 | 6,000 lb |
| 12 × 12 ft | 48.0 ft³ | 107 | 4 | 7,200 lb |
| 12 × 16 ft | 64.0 ft³ | 143 | 5 | 9,600 lb |
Worked example
2,000 ÷ 60 = 33.33, so 33 whole bags. 33 × 60 = 1,980 lb, 20 lb under the payload. 33 × 0.45 = 14.85 cubic feet of concrete.
Bags per load at other payloads
| Payload | 40 lb bags | 60 lb bags | 80 lb bags |

| 1,000 lb | 25 bags | 16 bags | 12 bags |
| 1,500 lb | 37 bags | 25 bags | 18 bags |
| 2,000 lb | 50 bags | 33 bags | 25 bags |
| 3,000 lb | 75 bags | 50 bags | 37 bags |
