Florida DOT Concrete Batchman/Operator Practice Exam

How many gallons are contained in one cubic foot of water?

1. 5.78 gallons

2. 6.50 gallons

3. 7.49 gallons

4. 8.12 gallons

The correct answer is: 7.49 gallons

One cubic foot of water holds approximately 7.49 gallons. This is based on the conversion between cubic feet and gallons, where one cubic foot is equivalent to 7.48 gallons. The slight discrepancy may arise from rounding, but the standard measure acknowledges this figure as the accepted value for the conversion. Understanding this conversion is crucial for concrete batching, as it informs how much water is needed for specific volumetric calculations, influencing mix designs and ensuring that the concrete achieves the desired strength and durability. Recognizing that 7.49 gallons fits this conversion underpins effective batching operations and helps avoid miscalculations that could impact construction quality.
