A standard truck load of concrete is around 10 cubic yards; for a pour 12x32 feet at 8 inches, how many loads are needed?

A standard truck load of concrete is around 10 cubic yards; for a pour 12x32 feet at 8 inches, how many loads are needed?

• A. Two loads
• B. One load was enough
• C. 9.49 loads
• D. 0.5 loads

Answer: (B)

Calculating how many loads you need starts with the pour volume and the capacity of a standard truck. Convert the dimensions to cubic yards and compare to the truck’s capacity. Volume of the pour: - Area: 12 ft × 32 ft = 384 ft² - Thickness: 8 inches = 0.6667 ft - Volume: 384 × 0.6667 ≈ 256 ft³ Convert to cubic yards: - 256 ft³ ÷ 27 ≈ 9.5 yd³ A standard truck holds about 10 yd³, so one truck load is enough to cover approximately 9.5 yd³. In practice you’d round up to whole loads, so you’d order one load rather than more.
