If it's about volume (which requires three measurements), without a third dimension, it's hard to calculate directly, but if we assume a uniform third dimension of, say, 4 feet (to keep in line with the given numbers), the volume would be:
A standard parking space is approximately 9 feet wide by 18 feet long. Half of that length is —the distance a driver typically needs to back out of a spot safely. It is also the average turning radius for a sedan. 4 39- feet
