If a subwoofer enclosure has a net internal volume of 1.75 cubic feet, how many liters is that approximately?

To convert cubic feet to liters, it is important to understand the conversion factor between these two units. One cubic foot is equivalent to approximately 28.3168 liters. To find the volume in liters for an enclosure that has a net internal volume of 1.75 cubic feet, you multiply the cubic feet by the conversion factor:

1.75 cubic feet × 28.3168 liters/cubic foot ≈ 49.56 liters.

This calculation shows that the net internal volume of the subwoofer enclosure, when correctly converted, results in approximately 49.56 liters. This matches the selection in the answer provided, demonstrating that the conversion was executed accurately according to the appropriate mathematical principles.
