A 50-m steel tape was standardized and supported throughout its whole length and found to be 0.00205 m longer at an observed temperature of 31.8°C and a pull of 10 kilos. This tape was used to measure a line that was ground to be 662.702 m at average temperature of 24°C using the same pull. What is the correct length of the line? Use the coefficient of expansion of 0.0000116m per degree centigrade.
