A 100-ft steel tape standardized at 68°F and supported throughout under a tension of 12 lb was found to be exactly 100.010 ft long. The tape had a cross-sectional area of 0.0075 in2 and a weight of 2.25 lb. This tape is to be used to layout a distance AB of 529.81 ft under the following conditions: 95°F, supported throughout, tension of 20 lb. What length is required to layout the specified distance?

ANSWER IS NOT 529.72
