How many BTUs are in a cubic foot of natural gas?

Explanation:
Natural gas provides energy per unit volume, and its approximate energy content is about 1,000 BTUs per cubic foot. This rough figure is the standard reference used in HVAC calculations to estimate energy input from gas consumption under typical conditions. The exact value can vary with gas composition and temperature, but 1,000 BTU/ft3 is the commonly accepted approximation. Among the given options, 1,000 matches this standard value, which is why it is the correct choice. The other numbers are not representative of natural gas’s typical energy density per cubic foot.
